There was a gallon storage bag on the giveaway table at the senior center of what looked like postage stamps, so I though I take it and look through it. It took me last weekend to sort through the bag. Most of the stamps I discarded (they were cancelled Liberty Bells and NFP stamps). I did find some more unusual ones, a block of "Officially Sealed" stickers, some Austrian Notgeld notes from 1920 and some first day cancellation envelopes . Any comments appreciated.
