This is an original painting depicting the jazz trumpeter. Jonah Jones (1909 - 2000). The painting is labeled by hand on the backside with the depiction/title of the subject, name of author of painting and date of completion. Leon Frederick Dragoo is not a listed artist; this was executed by a hobbyist artist. There is a listing for a Leon F. Dragoo who was born in 1943, so that would have made him about 19 years old when this was created. The estimate is based on actual past recorded auction sales of comparables.
