VTG PAINT BY NUMBERS WOODBLOCK RARE STAMP P511B, 40CC PALMER PANN CRAFT MASTER

Description

Unique woodblock from the Palmer Pann Paint Company which  started "Paint By Number" with Dan Robbins great idea and Max Klein being  open minded. My creative speculation is that Dan Robbins and Adam Grant actually inspected this or maybe better  just Max Klein and Dan Robbins, .....The Palmer Pann Company was created before Craft Master in the early 1950's.
This piece consists of a smooth piece of wood measuring 9 3/4"×13 3/4". It has a raised metal (not sure of type of metal) outline with some metal fill. I think the pictures best show what I am trying to convey....so look closely, please. Each area to be painted has the specific number. The color numbers range from 1 to 22.
This is stamped on the corner:

Thanks to a fellow Ebayer I have come up with the picture of a final painting. It is attached below with the info from the Great PBN Museum, go take a look for this and other neat pictures
My professional artist friends suggested that I try to make a print of this, but I decided it was best not too. I am unsure of what this piece should be called I know it's not an authentic woodblock, nor is it a linocut, not an etching plate, etc. I talked to a professional printmaker and he thought that this was of course used in the  early production days. A single color of ink perhaps put on the piece, the canvas layed on the surface  and a heavy duty metal cylinder rolled over the inked surface and canvas. He did not have a special name for this process either. Certainly not as fast as we do it now!
Overall dimension 9 3/4"×13 3/4" of wood
Please ask questions, request more pictures.  Feel free to correct me or add to the story.
This is a beautiful display piece, so far it's a great conversation piece amongst my artist friends. How many PBN aficionados have this?
