This is a vintage, 20th century, about 1960 - 1970's original floral still life painting signed Lehman in a carved wood frame from Mexico. This was not done by any of the listed artists with the last name Lehman. These were produced, oftentimes in factory settings in China and Mexico as quick original decorative wall art and sold through furniture shops. The signatures were usually fictitious names. This is not fine art for investment purposes. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
