Paint & Pencil
Paint by number (or painting by numbers) are kits, popularized in the 1950s, by the Palmer Paint Company and Max Klein among others. Included in the kits is a number board or canvas with corresponding paints to be filled in. Michelangelo has been credited by some with the original idea by assigning colors to various areas of the Sistine Chapel for assistants to fill in over some 500 years ago.
