Great grab bag of more than 350 all different unused U.S. stamps from the 20th Century.  Wide variety from the 1920s 2 cent reds to more modern issues, including air mail and BOBs, Souvenir Sheets. Most of the stamps are MNH, the rest are MLH or MH, all are in good condition.  Great way to fill in some of those holes in your album for just pennies per stamp!
