Sid & Marty Krofft Pictures

Background
Sid Krofft (born July 30, 1929) and Marty Krofft (born April 9, 1937) are a Canadian sibling team of television creators and puppeteers. Through their production company, Sid & Marty Krofft Pictures, they have made numerous children's television and variety show programs in the U.S., particularly in the 1970s and early 1980s, including H.R. Pufnstuf, Land of the Lost, The Bugaloos, Sigmund and the Sea Monsters, and Lidsville. Their fantasy programs often feature large-headed puppets, high-concept plots, and extensive use of low-budget special effects.

1st Logo (September 6, 1969-December 4, 1976, September 22, 1984-1985)
Nicknames: "Psychedelic Rainbow", "The H.R. Pufnstuf Logo"

Logo: We see a screen with many blacked-out words and sections, save for some spaces which are already colored light blue. Then various parts of the background are filled in with greens, oranges, and reds until we get a psychedelic-like background and the words "SID & MARTY KROFFT TELEVISION PRODUCTIONS" stacked on top of each other visible. All are in a disjointed sans font with tendrils coming off of "KROFFT" and "PRODUCTIONS" that have a "3D" look to it, and get filled in one-by-one from top to bottom (except for "KROFFT", which fills in first).

FX/SFX: The background and words being filled in.

Music/Sounds: There are three main music variants used on this logo:
 * 1969-1970: A twiddling saxophone/xylophone theme ending in a dramatic jazz stinger. In at least a couple of H.R. Pufnstuf episodes, the sound of canned applause and cheering can be heard under the music (carried over from the end of the closing credits).
 * 1970-1971: A series of "glug-glug-glug" sounds with 2 sets of 4 ascending synthesized chimes; the second one is much faster. It's similar to the music used in the Viacom "Pinball" logo.
 * 1971-1976: Same as before, except with different notes used at the end.
 * 1984: A very odd synthesized version of the 1969 jingle with an Aphex Twin-style stuttering snare drum after the first few notes.
 * In later years, the closing theme of the show was used.

Availability: Rare. This logo's last known sighting on TV in recent years was when Me-TV showed H.R. Pufnstuf in late 2013 (the logo is also present on DVDs of this show). DVDs of the original 1970s version of Land of the Lost retain this logo. This can also be seen on The Krofft Supershow, Pryor's Place, Sigmund and the Sea Monsters, The All Star Rock 'n' Wrestling Saturday Spectacular, and The Patti LaBelle Show.

Editor's Note: None.

2nd Logo (September 26, 1987-1988, June 5, 2009, July 10, 2015-)
Nicknames: "Psychedelic Rainbow II", "Rainbow Remake"

Logo: Same as the previous logo, but the text now reads "SID & MARTY KROFFT PICTURES", with "PICTURES" styled after "PRODUCTIONS". This also creates an uneven floor as well. The colors are slightly rearranged and are also far more saturated, with the replaced with, "PICTURES" being more yellowish, and the "O"'s hole in "KROFFT" now  as well.

Variants:
 * On 2009's Land of the Lost, the logo is in a box in the center of the screen on a black background. The colors are also less saturated.
 * Starting with Mutt and Stuff, the logo is animated like the first logo, but closer to the screen. It also uses the revamped colors.

FX/SFX: None, but same as the previous logo later on.

Music/Sounds:
 * For the original version, same as the 1984 music variant of the first logo.
 * On Land of the Lost, it's silent.
 * On Mutt and Stuff and the 2016 reboot film of Electra Woman and Dyna Girl, it's the 1969 music variant of the first logo.

Availability: Current, but may be rarer with older shows with this logo. Originally appeared on early episodes of D.C. Follies, and might have been preserved on Hulu. It was revived in 2009 for the film Land of the Lost and again in 2015 for Nick Jr.'s Mutt and Stuff, appearing on their current content.

Editor's Note: None.

3rd Logo (1988-1989)
Nicknames: "Psychedelic Rainbow III", "Psychedelic O", "The Weird Vortex",

Logo: We see an "O" spin out into the center of the screen. As it reaches the center, a psychedelic vortex explodes out from behind it and engulfs the background. The letters K, R, F, F, and T quickly fly around the O, creating the word "KROFFT" in its classic weird font. The rest of the logo then joins it, "SID & MARTY" from the top, and "PICTURES" from the bottom.

FX/SFX: Typical '80s CGI animation.

Music/Sounds: The 1984 music from the first logo.

Availability: Rare. Seen on later episodes of D.C. Follies. The logo is preserved on Hulu prints of those episodes.

Editor's Note: None.

(September 11, 1976-December 5, 1992)
Nickname: "Golden Shining Glass"

Logo: On a zooming space background, we see a -tinted glass block with "ENTERTAINMENT" embossed on the front, and "KROFFT" in a Helvetica font stacked on top of it. The logo starts off zoomed back and rotated to the right slightly, showing some lighting on the left, but it then zooms in and rotates into position while giving off a quick glimmer of light.

Variants:
 * There are filmed and videotaped variants of this logo. The videotaped variant has brighter colors, while the filmed is darker.
 * On the 1991 version of Land of the Lost, a copyright stamp is chyroned-in below the logo, which is also again filmed on this version, as the logo originated on tape.

FX/SFX: The glass text turning, the zooming space background. Very good live-action modeling.

Music/Sounds: A series of faint laser zaps with a dreamy electric piano stinger.

Availability: Rare. Seen on late-period Krofft shows like 1991's Land of the Lost, Pink Lady and Jeff, Best of Barbara Mandrell & the Mandrell Sisters Show and Electra Woman & Dyna Girl.

Editor's Note: None.
