For what it is worth, here is a drawing from the Tropical Graciology Group at Innsbruck university showing the difference in the Elena glacier between 1906 and 1990.
Obviously the 1906 photo we saw earlier is the basis for this drawing. It makes you wonder about how much of a photographic record we have from the pre-1950 era. It doesn't seem to be much. (I looked around and couldn't find another on the net.)
