Gee highlights the changes made to Fac 2 in the various editions of the Pearl of Great Price.
John Gee, A Guide to the Joseph Smith Papyri (Provo, UT: FARMS, 2000), [7]
While the original facsimiles of the Book of Abraham were made directly from the papyri, later copies were not and have progressively deteriorated, as illustrated here by Facsimile 2. Lines and figures that are missing from each edition are marked in color. Figures missing from the 1878 edition are also not on the 1907 edition. The illustration does not show distortions in the proportions in various editions.
