Illustrated book

The image shows a black line drawing of a roof on two pages of an illustrated book by an unknown artist. The roof has a curved shape and appears to be a traditional Asian-style roof. The roof is drawn in black lines on a yellowed background, which resembles aged paper. The roof's peak is pointed, and it has a decorative edge. The roof is supported by several columns. The columns are decorated with carvings at the top. The book pages are open, with the left page showing the left side of the roof and the right page showing the right side. There are some Chinese characters written vertically on the right page. The background of the image is white.
