on the back it stamped in red #114 BLUE BOY GAINSBOURG it is handwrtten Prom 308 either S or 5#63390 and the size is 20 inched and 17 in width its very yellow and also the canvas is nailed and stapled there is no signature that i can see and i have not attempted to open myself . in front at bottom of frame It can barely be read but I thing it says Blue Boy it seems this was part of exhibit but its seems like either this person probably passed away here in Hawaii there is not high volume on art so please forgive my ignorance and it was donated not knowing the history it looks very eery and In Hawaii when you see these types of art you do not bring it home almost like am omen to your home

i just know that it was the most highest paid painting and it was a bug controversy on the painting being sold to American and today Blue Boy is admired though out the world
