A venerable string pack presumably made by the company that became known as the Jewel Filipino Spinning Top Company. Made in U.S.A.
Compare with the Jewel string pack (2 strings for 5 cents), and the Jewel string pack #66 (3 string for 10 cents).
Although there is no date to indicate when this pack was made or sold, string packs that are "3 strings for 5 cents" suggest they are from the early 1930s.
