According to Christie Romero's "Warman's Jewelry, 2nd Edition," Art
Smith lived from 1917-1982. He worked in silver sheet and forged
silver wire, as well as in brass and copper. He is known for his
"biomorphic" approach, i.e., use of the human body as an inspiration
for his designs. He opened a shop in the Village, a few doors down
from Paul Lobel's (1900-1983), in 1948. Not all his pieces were
signed, but those that were, were signed in script.
I'm afraid that's all the info I have on him. Hope some of it is
new to you.
