white water takes black knight at rib 3

I was ready for a fire, I was prepared for a flood, but not for an insidious drip. In a binder holding decades a number have been changed- slow moving, dilute acid from an impossible series of events.
Thus far the negative the damage claimed I will miss most. There only ever was one print of this made and I donated it to a charity auction last year.
I think it resides somewhere in New Mexico now.
But that's all there ever will be.
