According to my notes, these paintings were done by Frederico Gumohon. I think they're really good, "Matisse meets Monet." (I didn't come up with that quote -I wish I could have-. Rather, I saw it posted somewhere in the booth.)
As I can't find anything about the artist on the web, even under simple misspellings due to poor handwriting, I'm sure I wrote down the name incorrectly.
