I had to look real hard to come up with something vintage that was red, white and blue and this is what I found. I'm sure a few of you will remember these stamp albums. This one is mine from my childhood and was never filled but makes a nice addition to my ephemera collection.
I found this info on the Protect America blog. It explains it nicely:
School children would fill an "album" with $18.75 of low denomination stamps, 10-cents or 25-cents, and hand it in to the post office in exchange for a War Savings Bond, which would mature in 10 years to $25.00. Adults could buy larger denomination stamps, place them in correspondingly higher value "albums" and trade them in upon completion for $50.00, $100.00 or higher denomination War Savings Bonds. The program continued after the Second World War, ending in June 1970.
Thanks for visiting and have a fun and safe Fourth.
