You nailed it on why those two rows were believed to be DP's for years. I was looking at the partial slit that Kevin posted last night and it occured to me where the belief that those two rows are DP's came from. When these 1957 sheets were introduced into the hobby in the late 90's I imagine very few collectors knew that Topps made 264 card super sheets that were two 132 card slits for each series from the mid 50's to the early 70's. The partial slit Kevin posted has those two rows printed twice so it was assumed that they must be double printed. They didn't realize that there were two more rows also printed twice on that slit and that there was an equal number of sheets that had the other four rows printed twice on it. The first slit is missing the Goodman row and the Klaus row at the top and the second slit is missing the Phillips row, Miksis row, Senators Team row, and Harris row at the top.
