These appear to be enamel paintings or silkscreens of two paintings by Thierry Ona. Each is signed ONA . Each is framed and matted. The back of the frames are sealed with glued, brown paper. The art itself is approximately 6" x 6" each. The art is very brilliant in colors and appear very shiny in texture. This is why I say enamel. I have not opened the frames. They are beautiful. I have looked on the internet for information, but have yet to find any about the artist biography or find any mention regarding the particular kind of art I have. All I can find is prints for sale. I understand John Simmons "[email protected] may know about these since he is giving/incharge of the current collection, but I have yet to hear from him. I believe the names of the two paintings are 'Dancers' and 'Ballerinas I'. All the best. Charlie.
