This is a framed image of a winter mountainous alpine landscape with homestead near water by Tom J. Dooley (1942-2010). From the images this appears to be a printed image on canvas. The use of the copyright symbol next to the name further indicates this is likely a bubble jet or giclee print on canvas.
The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
