This is a vintage early-mid 1960’s Bulwin-made Fender “Sunglasses” hardshell electric guitar case. This size is appropriate for all 3/4 Fender electrics, including; Duo Sonic, Musicmaster and Mustang. This incredibly rare case was an upgrade from the standard black vinyl rectangular cases. In fact, these cases are so scarce, that those which fit Stratocasters and Telecasters sell for upward of $2,000.00 on occasion. This case is in very excellent all original condition, though the original handle is missing. When it comes to cases, this is the rarest type and size, so if you have a custom color pre-CBS 3/4 Fender electric, this is the case for you.
