Have you ever seen one of these?

In the 1966 Fred Bronner scrap book, there are 19 of these items. They look like they could be some type of printing mold. Any knowledge on these would be much appreciated.

I am going to add all of them to the site when I have the time. The entire 1966 book is really interesting

They certainly look like they are artwork used for box illustrations, Anyone have printing knowledge on how they might have been used ?.

These are white cardboard impressions of the metal printing plates soon to be used- proof tests made to be sure the mirror image plates are correctly designed.

I also found this out about the pieces:

Pad-A-Matic was form or plate for offset printing, used for short runs of printing. Ink was added to 'positive' Pad-a-matic' plate, with the image transferred to a roller or 'blanket, then transferred again to the finished product - being the paper or cardboard.
