in 1971, Chuck Jones made a show during his short tenure as ABC's Vice President of Saturday Morning (yes, really) called Curiosity Shop - a show that was intended to compete against Sesame Street and has animated shorts based on Mr. Mum, Miss Peach, The Wizard of Id and most notably Dennis The Menace
As it stands, the show is lost media and worthy of a search
according to a YouTube comment there was at least one piece of merchandise aswell, a lunchbox. but that's a segment from the show and the intro in black and white, this seems super cool I wanna look for it too.
