I found this printing plate while scuba diving. I believe that it is very rare. I have searched for any ads or plates like this and can’t find anything. I think that this subject matter appeals to many different collectors. It is in great shape and could actually be used to print a copy of it. I rubbed a pencil on it and made sort of a rubbing of the image and took a picture which is in this listing. Printing press printer plate printer block.
