1996 Japanese Base Set Mewtwo holo, PSA 1 Poor.
Yes, a 1. There is a crease through the centre of the artwork, the corners are rounded, and the back has scuffing. It is graded, authenticated, and honest about what it is.
Buy this if you want the art on your shelf for a tenth of what a clean copy costs, or if you collect low-pop grade extremes. Do not buy it expecting to crack and re-grade.
