Original Police Photo Printer's Blocks 1930's

Pictured are 60 original police department photo/printers blocks, which contain the copper or bronze photo negative attached to the wooden block, which made the exact pictures in photo 1, which were used in policemen's balls advertising books. The pictures I took doesn't do these justice, as when you ink them, the photos come to life, and look really cool in my display curios. Many of these are from the 30's, but some are older than that, as a few of these officers were with the department in the early 1900's. Enjoy!!
