Noticed that my T205 Gray - no stats card has on the bottom boarder in the gold area, a 3 line and a flower kind of image on the right. The lines that doesn't show well as they are a diffrent hugh of gold. Also under photo image is also some small triangles and more patterns. It can be viewed best in full sun at a steep angle. I've shown this in a black and white photo that shows better.
More photos can be found in my Net54 photo album under t205 gray folder.

I researched the T card catalog of the ATC for
all card series that has gold boarders including T42, T43, T80 and many more. With no exact match, the closes being the corner design of the T43 bird series #30 of the Vermillion Flycather witch has same or smiler flower design but not the 3 lines. I can find no card with a 3 line pattern on it.
Please check your T205 Gray card to see if you can see same markings and any ideas you have about possible overprinting.
