THIS VINTAGE ANSCO DARKROOM DOOR SIGN WAS APPARENTLY USED FOR FILM PHOTOGRAPHY.

 IT INDICATED FILM WASH START AND STOP TIMES.

 MY UNCLE WORKED AT ANSCO IN BINGHAMTON, NY IN THE 60'.  IT  WAS  HUNG ON A DOOR IN THE DARKROOM  OR WALL AND   ADVERTISED  ANSCO JET PAPER.

RARE FIND I HAVE NOT SEEN ANYTHING LIKE IT ON EBAY

IT MAY BE TIN BUT NOT SURE Appears laminated.

Dimensions  8 1/4 by 10 1/4
