Old photo help

[jtw1313]

This photo is like a hologram you can only see it one way then it disappears and is like a mirror. I know the process of these old photos but can’t find any that totally disappear. And it’s pretty much all silver. Anyone have any thoughts

Melaniotype image. Not as popular as the daguerreotype and both were phased out by silver halite on acetate.
