I can confirm that upside down White & Doyle have matching backs. It might not be super clear in the scans but I have both in hand and they match. This means that these two cards are in opposite positions, equal rows and columns from the center, sides, top/bottom, horizontal axis, etc. If we can link either of these two to a center/side/each-other via scratch we could make a lot of progress quickly. I look forward to seeing any scratches, neighbors, two-namers, etc that you have. Another piece in the sheet-size puzzle...
