I don't know. I own 5 Revenge of the Jedi posters, 2 rolled dated, 1 folded dated, 1 folded undated and 1 rolled undated. They are buried somewhere, so out of reach, but the one thing I know for sure is that the undated version is slightly smaller than the dated one. I never noticed a difference in size among the dated ones, folded or unfolded, but I could be wrong.
