What is a united profit sharing corporation coupon?

Are they worth any money?

These coupons were given when gasoline was purchased back in the 1930's. You could order items from a catalog (just like grocery store stamps). I have an invoice dated 9/3/41 for an 'ICE CUBE BREAKER' sent by Bennett Brothers, Inc, 485 Fifth Avenue, New York, NY (invoice N151722). My 94 year old mother gave me a stack of them recently. She said my father gave her sister a camera he got with some of them.
