Chemicals changed this color, it is not a scrap

These look a lot different from some of the ones that people here are saying were caused by chemicals/glue.

For instance, the Bates on ebay is clearly only missing the blue in the background - the chemicals or glue had no effect on any other color. Not saying this doesn't make perfect sense, but it's odd how these chemicals/glue resulted in such odd patterns on other cards, such as the ones in the Mastro auction.

I have no special knowledge about this process - just asking questions as part of the discussion
