Photo blocks ?

[mojjax]

Does anyone know what these are called . I'm trying to find out how to clean them . I think they are for printing newspapers . They are engraved copper plates on plywood blocks . The first one is hard to see because it's so dirty, but it's a floor plan of a school . One is a group of girlscouts . And the other is a couple and their baby .

Ask a printer how to clean them and then print them. Bob
