The calligraphy is written in black ink and consists of about 30 lines of text. The calligraphy is written vertically, with the top line at the top of the artwork and the bottom line at the bottom. There are two red seals or stamps on beige background, one on the left side near the top and the other on the left side near the bottom, both written in red ink. The artwork appears to be a traditional Chinese calligraphy piece. The title of the piece is "Poem on a Riverside Pavilion" and the artist is Wang Duo.
