Imagine giving children poisonous crayons. Apparently, in 1915, that wasn't an unthinkable prospect. Why else would the Standard Crayon Company find that an important advertising feature for the Murillo drawing crayons? This is a scan of an actual ad I found in a children's magazine dated 1915. You didn't even have to buy them with money. For fifteen cents in stamps you got the crayons and some kind of coloring book. What a deal! (file 1915_crayon_ad, #590846)
