When we were in Sosua we doubted about buying a painting. Not the ones you see at every corner, but we saw some interesting real paintings @ a shop near the Sosua beach. It was an art gallery, i think that was also the name of the shop "Art Gallery".
We saw paintings of, if I remember well, a painter namend Agustin.
Does this ring a bell at anyone?
Doesn't anybody live in Sosua by coincidence?
Just walk down the beach, look on your left hand for the art gallery. On the right wall you see a painting of a woman with a hat on the beach, and a painting of a person screaming in the jungle it seems.
Can you check what the painters name is?
