Thanks again for all the responses.

Many have pointed out the existence of 1904 Conlon photos with borders, some stamped with his early NY address. Because of the stylistic and size differences with his other early prints, it is at least questionable whether Conlon developed the prints and exactly when they were developed.

During the decade between 1906 and 1915, Conlon primarily developed numerous contact prints and larger prints, mostly 8" x 10"s. In connection with these prints of his 1906 to 1915 photos, there are none known with the full white borders.

Advanced collectors have checked with the Getty Museum, the Met, and other leading museums and conservators about their ability to determine the dates of early twenty century photographic prints based on paper or fiber analysis. The best reliable analysis that these conservators could make is a date range within approximately ten years. Consequently, PSA's claim that the Cobb sliding print was made between 1910 and 1912 is difficult to swallow, especially because of the lack of other bordered Conlon prints made between 1906 and 1915 from contemporary photos.
