1950s Demo Reel Tape: Fun, Unheard Tunes - Big Band, Patriotic, Orchestral

An oddity found in the Marchant collection - a tiny 2” reel published by “A-V Tape Libraries” - a tiny and long gone commercial reel to reel label. This is a demo reel - the back of the box says:
-------
This is a special sample reel of PRE-RECORDED MAGNETIC TAPE and contains
excerpts from the music catalog of A-V Tape Libraries Inc.
This reel has been pre-recorded at 7.5" per second. It can be played on all home-type tape machines.
Use it to demonstrate your stock of A-V Tape Libraries ... with our compliments.”
