Set of four vintage Bottoms Up satin glass shot glasses rare split leg McKee ? For Sale

Four rare split leg bottom’s up shot glasses, in excellent condition with no chips or cracks. White satin glass, measuring 3 1/2” tall and 2 1/2” at widest point. The split leg design was earlier than the closed leg version, and cannot confirm if it was McKee glass. This was not reproduced, to the best of my knowledge. One glass has a tiny bubble on one buttock, from manufacture. Thanks for looking!
