Thank you for submitting your item for appraisal. This appears to be a chinese production line painting from Dafen. The asian - alpine - forest - lake - mountain landscape painting is a clever combination of repoussoir motifs, foreground and background and very likely appealed to the previous owner. Such paintings are still being produced in the painting village Dafen in China. You can order similar for one dollar without stretcher and frame. The estimate is based on similar sold at auction.
