Here is a large 5 X 4 inch glass black and white negative picture of a men in aprons working at tables or large trays - possibly print or type setters.  This slide was from a collection purchased in an estate sale and I have no further information about the slide.  It appears in overall nice condition.   (My apologies for reflections and glares in my pictures - the glass negative is very reflective.)     Please see pictures and ask any questions. 

Thank you for looking.  (Inv 26,007)
