Abstract: A device to label photographic films carried by structure including a frame, comprises(a) a template in the form of a transparent, generally planar and rectangular sheet adapted to carry an image to be reproduced on the film,(b) the template having retainer tabs projecting at multiple edge portions of the sheet to removably fit beneath said frame to retain the template to said structure so that the main extent of the template overlies film carried by said structure,(c) the template having a limit tab projecting at one edge portion of the sheet and outside the plane of said sheet to engage an edge of said frame for preventing removal of the template in response to endwise removal of exposed film from the carrier structure, whereby the sheet remains in the path of light transmission to unexposed film carried by said structure.
