Zoetrope strip entitled 'Tuck in Your Twopenny' by the London Stereoscopic and Photographic Company.

A zoetrope strip is a strip of paper with a sequence of printed drawings representing a scene in motion which sits inside a the drum of a zoetrope. When the drum is rotated, the images provide a loop of continuous motion. "Tuck in your tuppenny" derives from rhyming slang. It means "tuck in your head". Rhyming slang gives "tuck in your loaf of bread". "Loaf of bread" becomes "tuppenny loaf" and then "loaf" is dropped. "Tuck in your tuppenny" was a useful instruction if you were playing leapfrog, as the characters in the strip are.
