Budweiser Printers Watermark Metal Die Block 1933

Description

Budweiser Printers Watermark Die Block Metal 1933
Die is marked Thor PGH STAMP CO. and dated 5-33
Measures about 5 5/8" in Length and 1 7/16" Wide.  When laying down it is about 1/2" Tall not including the raised lettering.
Die weighs in at 1 Lb 3 ounces and is made of solid metal.  A magnet does stick to it.
The inside of both the letting and stars are recessed.
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 and some patina to the metal.  Overall still presents itself well for a shop used piece from 1933.  Please review all photos and judge for yourself.  Use
