Those are some seriously amazing cards guys. Thank you for posting.
Here are some of the Lenox backs I have owned over the years:

Only the McGraw remains in my collection, however I am very happy to have recently acquired a quality Brown Lenox (my first ever Brown) in the recent Robert Edward Auctions. I do not have scans as of yet but will post them soon.
Great stuff guys. Thank you very much for sharing. I hope this turns into a loooooong thread
