Alice and I in our favorite position, with our favorite socks.

My father passed away when I was a child and I kept his briefcase that reminds me of him (he used this every day in the late 1950s - mid-60s). I estimate the briefcase is now 65+ years old, and I've never attempted to clean or condition it because (confession) I never learned how to care for leather correctly.

Being old and neglected was bad enough, but the briefcase suffered further insult about 30 years ago when my sister's massively-sized dog (named Gorilla) peed on it when I was living with my sister's family during an internship near her. I assumed the stain immediately became permanent (it was soaked in and almost dry by the time I found it). Gorilla was quite proud of himself and did not respond to reproach, except to thud his tail on the floor innocently.

Heartbreaking damage to a beloved memento of my fathers, and I think I know the answer, but I have to ask leather experts, is there any hope to minimize or eliminate the stain and to restore and renew the leather?
