Savings stamps were all the rage in the mid-20th century. Consumers would collect the stamps with their purchases and fill up books like these. Stamps were given at J.C. Penney's, gas stations, groceries and lots and lots of other places. Once full, the books could be traded for merchandise. This has been replaced today with rewards cards - but the idea is exactly the same.
There's something to be said for actually being able to touch the stamps and the books. I remember going to the S&H Green Stamp (another brand) outlet with my Mom to pick out things like a cooler or thermos, small appliances, umbrellas and more!
There were many brands of stamps and Blue Chip Stamps were quite popular - the cute little chipmunk on the front of the booklet made them memorable.
These books are totally unused - there are no collectable stamps inside. So, you can use them to alter, to collect your own stamps, or just as a collector's item.
