BIG OLD BLACKBOARD

Fantastic large old blackboard! This is one of 3 that came out of the Physics department of a NYC University. Big about 4' x 6' .Take it home practice your math, your post mortem body tracing, or whatever you like. Can be mounted horizontally (for which we have the original chalk tray that attaches to the bottom) or vertically as shown.
