Thank you for submitting your item for appraisal. This appears to be an oil on canvas painting by William Moninet (1937 - 1999). The artist was born in Louisiana and later known for his impressionistic depiction of sad or happy clowns. He was very industrious and produced a large number of paintings. The estimate is based on similar paintings sold or offered at auction. There is no measurement for the sentimental value you might attach to it.
