A home on the Mississippi by currier and ives

This was my grandparents' piece. My grandfather refinished it. The roll top is in the open position and we are not sure if it will easily roll down. We didn't want to pull too hard on it.

We believe this is an Oak China Closet from the late 1800's or early 1900's.

This was my grandmother's lamp. We believe it is from the late 1800's.

I was given this a few years back and I have no clue where it is originally from, and i know nothing about easels besides the fact that this one is VERY special.

I saw some that went for thousands of dollars on google.

Its is the 55" inch tall version of this easel.

From what i can see on google, they call the style "Rococo Style" if I understand correctly.

It is fully made of massive Brass and has 3 stamps indicating some kind of serial number.

This tennis racket was left to me by my father when he passed away. I have no idea about any history on this. It has been kept inside the home with temperature control for many, many, many years. Could someone please tell me about it and the value?
