I have been a member of the United Postal Stationery Society for the last 5 years. Its been worth every penny of the membership fee and more. I learned the ins and outs of US postal stationery, its so much fun looking for different dies, watermarked, knife, size and so much more. I highly recommend any collector to join this society.

I recently acquire some US possessions postal stationery (Canal Zone, Philippines and Hawaii). There is a duplicate set of 5 Canal Zone cut squares pictured above. The first 5 people that correctly identify these cut squares will receive a nice MNH copy. Send me your answer to localpcguy at gmail.com
