Water-sensitive photographic materials

We have a few photographs in which both the print and negative are
water-soluble.  They a labeled that they where made in 1921.  Would
anyone know what process they could have been made with?
Unfortunately the prints and negative where kept in the same
envelopes, and one of the prints has struck to the negative.  Is
there any way of separating them?
