UCLA History: Blood Test In Case of Atomic Attack

Caption reads: Blood type kids as A-Bomb precaution at University Elementary School, part of University of California Los Angeles, June 6, 1951. Fellow first graders watch as Lester Wilson - 6 years at right submits to needle; Bob Appel (lab technician); all kids will get ID or "dog tags" with blood types listed.

Note: The scribbling on the negative can be partially read by reversing the image (mirror image) and turning it upside down. It appears to list the names of individuals in the photo.
