Marking photographs

From: Linda Sootheran <*sootheran*> Date: Monday, January 18, 1993 · sootheran

We are having difficulty finding a writing instrument that will mark on
the back of photographs.  Is there a special type of pencil to use?  We
are interested in what other libraries do to identify photos.
