Music buying store counter display

Rare! Cool! Old! Music store counter display for "Coast Quality Mouthpieces." Coast was a brand of wind instrument mouthpieces from West Germany. We don't believe it is in business anymore.

Display is 12 inches high, 12 inches wide and about 5 inches deep.

There are shelves in the back - unclear if these were added later or if this was part of the original construction to hold the mouthpieces.

The buying paint and graphics are bright! There are a couple of large chips (see pictures) and it is in overall vintage well-used condition.
