1958 Topps Hank Aaron - BLUE background??

I like that 69 rookie stars card!

Some of the variations that are recognized are indeed just printing mistakes.
And there are some that aren't recognized that are differences on the printing plate. Some from damage, some from mistakes in making the plate.
That's how I define a variation, a difference caused by the plate being different. There aren't many people that go with that for good reason. With the access to the internet images a vast number of differences get noticed. Unfortunately, lots of the ones listed on Ebay are just transient print defects. And that added to how inconsequential most of the actual ones are makes collecting them seem silly to many collectors.
The Thomas NNOF is a mistake in making the plate, somewhere along the line a chunk of debris got between the mask (negative) and the plate causing missing areas.

The top two cards could be similar, or might just be cards where a bit of paper or something got into the press and blocked the black layer.

I'm working at typing up a list of variations for 81 topps. Nearly all of them really trivial, but actual plate differences. (I had lots of time, and about 15 thousand of the things to look through. )

The Blue Aarons might be fading, but usually either the red goes first or the colors fade a bit more evenly. If they're not fading then it's just a missing color. A nice and really interesting print error, but not a variation even by my loose standards.
