Where can I give art to someone who might resell it?

My father just passed and I am trying to find a place to give his art. There are some framed paintings and a lot of statues and a lot of plates It is all good quality, in excellent condition with certificates of authenticity. it's all nature/bird items, so perhaps a very niche market.

I don't want any money from it, I just want someone to have it who might get it to others that want it.

Any idea in the Milwaukee area of someone who might be able to do something with this?
