Sorry, this item sold. Have Pikurpie make something just for you, or try these other items:
However, I am not positive if it is the same person.
Cover mailed to Willards Hotel Washington DC with an unknown postmark on bottom; possibly New York
Professor Paterson MC 264 F Street is noted in pencil top right.
Part of the flap seal is missing on back and cover does have some dings on the edges.
This would make an excellent addition to any collection.
