Name That Trauma :: Kinderpal Brother Bill of The Haunted Closet on a Creepy Crack

After lurking at Kindertrauma for several years, I FINALLY have a Name That Trauma request worthy of the site. I've had a run of good luck tracking down spooky books and films that haunted me as a child, from the haunted house oral hygiene film I saw in 2nd grade (The Haunted Mouth), to the pair of creepy anthology books I used to check out from the school library (Roger Elwood's Monster Tales and Horror Tales), the classroom vandalism film that never let go of my soul (The Boy Who Liked Deer) and the disturbing image of an exotic dancer biting off the head of a live snake that I needed to exorcise from my subconscious (Stanley!)

But there is one fragment of a memory from early childhood that I've never been able to locate. A short animated piece (I remember sparse black-and-white line drawings) where a little girl or boy is in the bedroom and a crack on the wall starts moving, talking, and forming different shapes. I remember it finally formed a monstrous, scary face, before freezing and becoming just a crack in the wall again. I want to say this was on SESAME STREET or ELECTRIC COMPANY, but not sure. This would have been in the early-to-mid '70s.

In my own search on-line, I find reference to this film in talkbalk conversations by other people also desperate to identify it (the consensus seems to be it was from SESAME STREET, possibly called "Crack Master") but no one is 100% sure, nor does anyone have a screen capture or video clip of the film… any help?

Thanks, Kindertrauma!
