I got these books from my parents and have no idea what type of value they hold.

Bowls of the Great Trek of the Boers in South Africa. Some made in holland and small bowls by Mason England

I have a drawing of chief sitting bull by vera Louise Drysdale I want to know what it's value is

Bought this dresser from an estate sale:

Drexel Walnut Dresser, Repertoire, 519-132. 

I have no information on this except the lady that had it never used it. It sat in a sitting room for 70 years so slight discoloration from other side of the seat cushions. Also the cushion filler is so old it's crumbling to dust. 

I tried searching for a tag for the maker of it with no luck. It is very heavy (compared to my sectional at least) and has wood and bronze cone shaped legs. 

There is an arm cover but I didn't put it on for this picture.

Any info would be so appreciated!

Queen Anne style five drawer highboy dresser made of mahogany or maple. Full bonnet top and capriole legs. Dovetail drawers. Circa 1900.
