I don't own this T215-1 Griffith anymore(and took the T206 scan from ebay). The T215-1 belongs to another board member but it was in my collection for years. You can see the background shading be different......however it is more pronounced (much more) on different cards. I am not sure this isn't just a printing plate issue though. Even regardless of this I have never heard T215 be talked about as being T206.....as the T213-1 has..
best regards
ps..btw Brian- as you are throwing out different scenarios about different issues I applaud you for it. I am the type that thinks everything should be questioned and inspected
. Now, about an actual change, I am much slower.
