this auction"Alright you Moog fraks, check this out! This is a display case designed and built specifically for the Minimoog. Show your Minimoog with pride in this display case. It has a plexiglass window, veneer covered wood panels, foam padding on the inside walls, a spot for a cooling fan, and some ventilation slats in the back. SWEET! There is one corner that is a little rough but it could be fixed very easily with

some glue or a tack. Local pickup in Los Angeles area only!"
For the true collector in you, or as Nick who sent this to the AH list called it, it's the "Minimoog Bubble Boy." Seinfeld fans should get that one.
Apparently its an old "dot matrix printer noise isolation box."
