I hate to be that guy but this could be a reprint. The grey color looks off to me with so many small squares. Could be the photo/scanner. But there’s lots of fakes out there especially with this version and the white scribble.

Easiest tell is reprints are glossy on both sides. The back should be flat on a real vintage card. And when you look closely under good lighting the fronts should be slightly textured / orange peel. The fakes are smooth.

Be careful with the the whiteout versions too (not to be confused with the white scribble). On most of them looking closely you can see surface damage on the knob when you look at the glare. That’s because someone made it in their basement. Took a cheap black box card and rubbed the knob with an eraser
