Arts and Crafts

What does art contribute to the world’s economy?

How did the Arts and Crafts movement influence modern design in the USA?

Is anyone doing some rehabbing and want to share?

I understand Art appraisers examine and evaluate paintings, sculptures and antiques to determine the authenticity and the market value of the subject art they appraising by identifying the creators and the quality of the art. Art appraisers thoroughly inspect, evaluate, analyze, and examine the artwork’s color values, brushstrokes, lines, engravings, and other factors in order to identify the artist and date of creation. But can anyone tell me what does an art appraiser do to come up with what the art is worth and is art appraisal a uniform set standard or is it arbitrary. How do you determine what a piece of painting is worth. What determines such high price for art.
