Found in the USA - Sunday Stamps

I did not expect to take part this week as I am staying with my daughter in Michigan. However I 'found' some stamps in her desk so here's my photograph.

USA

These are from the 'Celebrate the Century' series and represent the 1940s with the jitterbug, abstract impressionism and the post war baby boom.

I shall have to see what else I can find for next week.. Meanwhile enjoy other finds at Viridian's sunday-stamps-73.
