20 stamps per glassine envelope - all stamps will be excellent condition and unused

These are all very old postage stamps, from many years ago before the age of "self-adhesive" stamps. 

These ARE still valid useable USPS postage. To use these you must lick or otherwise moisten the back to activate the glue.

A variety of different random stamps in each lot. Each lot of 20 stamps has no repeats! (but if you buy more than one envelope, the chance of repeats will be introduced)
