I've compiled the checklists from the new T206Resource site into a "master" T206 front/back combinations spreadsheet.
I wanted to make it available to anyone interested so I've uploaded it to Google Docs (it's free). Here's the direct link:
T206 White Borders Master on Google Docs
The folks at T206Resource have been kind enough to create a page with instructions on how to save it to your computer for personal use:
Instructions on How To Download the Spreadsheet
And before anybody gets bent out of shape over acknowledging prior work, I'll be the first to say that all of the T206 front/back combos that have been confirmed (and the determination of the no-prints) could have only been accomplished with the input of many, many collectors. There are some works that especially stand out in my mind and include:
Bill Heitman's "The Monster".
Scot Reader's "Inside T206".
Bill Brown's "Super Set" spreadsheet.
Ted Z's numerous surveys here on Net54.
Best Regards and Happy Collecting
