Card Identification Forum

Hello everyone, I recently bought a large collection with a great mix of vintage cards from the 50's all the way up until the late 90s. I still have a lot to go through but I came across this card and was wondering if anyone knows why these colors are different. I tried to research this and came up with nothing. The back of the card looks normal to me as well. Any help is appreciated.

Looks like it missed the yellow plate.

This card is sun faded. Most likely sat in shop's case exposed to light over the years. You can see that the yellow is faded but still present. 

My initial thought was also sun faded.

I was thinking that as well but I thought that seemed a bit extreme to go from that green it normally is to this blue. Sun faded does make the most sense however, thanks.

Agree.
