Found this T206 missing magenta in my collection.

For those with the sunlight theory - Yes I guess it is possible......however, I think you would see a faint outline of the lettering which is not visible on the Carrigan.

The glue on the reverse to me would mean it was in a scrapbook which I doubt was left open to that page for an extended period of time in the sunlight.

Didn't you know? Glue and/or sunlight both totally suck all traces of magenta right off of cardboard - sunlight accomplishes this feat from the front, glue from the back. It's true. You could test it yourself, but the tests take a long time to run. How long? Nobody really knows, but if you go read old hobby publications, you'll probably see stories about 'red background' cards that have glue on the back and the magenta appears to be slowly evaporating

It was a huge mystery back in the day, but nature's testing is finally completed.
