Here is a CD 190/191 TWO PIECE TRANSPOSITION with the mis-spelled TRANSPOSITON on the bottom piece. The color is a blue aqua. The condition is good with some of the normal roughness at the top of the pinhole on the bottom piece, a couple of pinpoint ticks, and a little nibbling / flaking around the base of the bottom on the overpour as seen. It comes with a clear acrylic pin. I am asking $12.00 plus actual shipping to the lower 48 not to exceed $10.00.
