Loyal Order Moose Printers Watermark Metal Die Block 1949

Description

Loyal Order Of Moose Printers Watermark Metal Die Block 1949
Die is marked Thor PGH STAMP CO. and dated 11-49
Measures about 3 3/8" in Length and 3 3/8" Wide.  When laying down it is about 1/2" Tall .
Die weighs in at 2 Lbs and is made of metal.  A magnet does stick to it.
I was told that this die was used by the Hammermill Paper Company in their process of putting watermarks on a company's letterhead or stationery paper.  I was told the process involved pouring a sort of liquid rubber onto the die and when cooled it was peeled off and used to make watermarks during the printing process?  I cannot confirm this but it does seem different than normal print dies.

condition.  Die shows some wear in the form of scratches, dings, tool marks and some patina to the metal.  Overall still presents itself well for a shop used piece from 1949.  Please review all photos and judge for yourself.  Use
