The definition of Type I versus Type II is stated from Henry Yee's usual wonderful assortment of photos:
Type II photos thus may be printed approximately 2 or more years after the original photo was taken and from the original negative.
For a photo taken in 1910, how is it at all possible to tell whether the print was made in 1910 or say 1916 or 1920? In the 1980s, I printed copies my own photos from the original negatives several years apart and now a number of years later, I can't tell which were printed first. Is there a leap of faith required on the authentication of Type I versus Type II photos or am I missing something?
Thanks,
