I have been given a group of framed prints of US WWII and earlier planes, 16" x 14", printed in Dayton Ohio July 19, 1997, and containing 'FIRST DAY OF ISSUE postal stamps with each planes picture on the stamp.
I'll probably keep them, but would love to know what they are worth (if anything).
Anyone familiar with them?
I attached a partial scan of one.
Thanks
