Vintage TART OPTICAL Unknown Model Mink C.B. This is a very rare horn-rimmed model with a SADDLE bridge, featuring diamond rivets, not even listed in the catalogs of the time, and with an ARNEL-like appearance. While it looks similar to the ARNEL at first glance, it has a slightly different lens shape with subtly squared-off lower corners, a saddle bridge that gives a cleaner impression when worn, and temples with a shape unlike any other TART model. This is a high-level frame that encapsulates the TART aesthetic and taste, and it wouldn't be out of place as a main TART model. The raised bridge and end pieces of the front, along with the recessed lens frame, create a design that functions as nose pads, showcasing the rational aspects of American eyewear aimed at improving productivity. Even among the original USA-made TART OPTICAL, where mysteries still remain, this is a particularly unique piece. There are minor scratches that are not easily noticeable, but it has a shine and is in relatively good condition for a vintage item. The diamond rivets and hinge hardware are free of rust and have a luster. There is no frame twisting, loose screws, loose hinge hardware, or oxidation odor. This is a very rare and hard-to-find item, so we hope you will consider purchasing it at this opportunity.
