Trying to remember the name of a toy from 1960s

It was a plastic box with a handle at the top that you would put scrolls inside and the box acted like a frame.

Turn the knob at the top of the box and the scroll would roll up; turn the knob at the bottom and the scroll would roll down.

The scrolls (and you could by more of them at the toy store) had various games and puzzles and mazes for you to play and solve.

And on the back was a “secret compartment” where you could store the crayons and cloth for wiping the scroll clean after you solved all the puzzles.

I remember those but the name is also evading me.

Very similar in execution to the device used in the old Concentration board games.

Snorri, it was called a Colorola. Made by a company called Norstar.
