In 1993 at the Altoona Public Library an inventory was made of the PRR photograph negatives in the collection for transfer to the Hagley Museum Library. It was found that there were large gaps in the number sequences and a large number of gaps.
About a third of the negatives in the number sequence are missing. This means only the prints now in circulation are the last archive and the only clue to the contents of a print missing from the inventory is just a number.
The photographs shown in this gallery are some of those numbers missing from the 1993 inventory, now found for viewing. A few shown of the 41 are in other galleries. Here is a list of other photographs missing from the inventory already shown in other galleries: E665G, E14846, E14848, E15094, E19125, E19126, E20365, E22271, E22667A, E22667B, EE1627A, EE8039, EE8083, EE8793, EE8794, ME15G, ME56B, ME60C, ME146, ME213B, ME437B, ME438B, ME439B, ME440B, ME487B, ME807A, ME808A, ME817A, ME818A, ME819A, ME820A, ME821A, ME822A, ME824A, ME825B, ME826A, ME827A, ME829A, ME830B, ME921A, ME1002A, ME107A, ME1009A, ME1210A, ME1275A, ME1277A, ME1284A, ME1311A, ME1312A, ME1313A, ME1316A, ME1318A, ME1791A, ME2962
