I am beginning to wonder if you simply do not get it or will not get it.It advertises what??? That you took Grandma’s old fur and recycled it??? Are you going to put a sign on your back saying “I recycled, but don’t do what I do–BUY NEW!”
If someone looks good wearing a mink coat, other people looking at it may well be impressed to go buy one themselves.
Antique or not is irrelevent unless the observer is aware of it.
Like I said, it advertises.
