Lebanon Art Guild is run by volunteers and artists. It is closed Mondays, but open Tuesday through Saturday. Some weekend evenings, they even have free live Bluegrass music.
The artists showcased are constantly changing. Some are so-so, some are fantastic. Prices range from $10 on up. The displays are always different when I go in there to look around. The people who volunteer will tell you all about the artists displayed or recommend other artists you might be interested in seeing. The volunteers are there to educate and entertain you.
