A place someone would not think of buying a box of Crayola Crayons would be their local post office. But in 1998, the USPS sold a set of Color Your Own Postcards that included a box of 8 crayons in a 1903 reproduction box. This also coincided with the release of the 32 cent Crayola stamp. There were 5 each of 3 different postcards one could color.
The crayons in the box are the 8 basic colors, black, blue, brown, green, orange, red, violet, and yellow.
The back shows the 3 postcards available in the set.
