I found this small framed painting, of a tree, half in daylight and half at night, at a butterfly sanctuary along the road around the rim of the Ilopango Lake crater in El Salvador. Apparently the artist had asked the owner of the butterfly sanctuary, mariposario, to help him sell his paintings. This beautiful small work of art is on canvas, wrapped tightly over wood.

This lovely painting measures 6 x 4 1/4 x 3/16" (15 x 11 x .5 cm)
