Print blocks were used my newspapers back in the day to set type or ads in their periodicals... The are wooden with a metal layer on top..
These are made in reverse so when used tge print shows as normal... They are typically on the smaller side for films but this one measures a very large 1 X 4 X 10.75 inches for a very large ad placement.... Comes in used condition with age and storage wear... I have reversed the LAST photo to show how the ad would actually appear....Due to a rash of non- payments... Our items come from a wide variety of sources and may or may not have been exposed to pets and/or smoke... I apologize but these only waste our time and yours..
