I think these may have some minor value to them. Not that I would sell them, but it would be interesting to know.
According to back of these prints, they were given to someone, perhaps family or close friend from a late persons estate.
They were framed back in 1974 or at least someone addressed the back of them in 1974 when they were given to "Elizabeth". So I'm pretty sure that these aren't recent copy's. Anyway, I really like them and think they will hang in my bedroom.
