I believe this was done about 100 years ago by Theodore Fresson . . .
unfortunately he and his decedents have kept it a trade secret.
I also think they look better than gum prints . . . much deeper shadow
tones and highlights that seem to glow.  If done well they make a very
stiking image. 
If you are interested, I can forward you some formulas that I believe are
on the heals of the Fresson secret.
