The Mustard Seed Garden Painting Manual

The Mustard Seed Garden Painting Manual by an unknown artist. The image shows a book lying open on a white surface. The book has two pages, one blank and one with writing and a red seal. The pages are yellowed and have a rough texture. The left page is blank with a few dark spots and stains. The right page has a black border around the edges of the right half. Inside the border is a vertical column of black Chinese characters. Below the characters is a red seal. The background of the image is a white surface. The book appears to be old. The pages are slightly curled at the edges.
