The Alex Johnson shown below on the left was not an upgrade, but it was a variation that I needed.
The new version is in horrible condition. That's okay by me. I didn't notice anything else about it until I added it to the other cards in my not-yet-completed master set. The damaged one doesn't have "1970 Xograph" on the back - it just has "Xograph". It also has the CA logo instead of the Angels logo with the outline of the state of California.
The picture above is not a mistake. I flipped both cards over (horizontally so that the front is still properly facing up) and found that the one on the left is printed with the picture on the bottom left while the other one has the picture on the top right. I have at least 300 damaged 1971s and all of them show the picture on the top right.
Does anyone else have any examples like this?
If you've been reading my blog, I've got nothing better to write about than to look at stuff like this. If there are variations of everyone like this, then I will never finish this master set and I will wish that I never noticed this oddity.
