Thank you for contacting Mearto. These are two shanshui (mountain water) paintings, likely of Chinese origin. They are ink on silk. The red seal marks usually are that of the artist, collector, or time period. The calligraphy is usually the name of the artist, in this case, it appears to read: 烹泉 Pēng Quán. The name and seals do not match with known artists.
As a pair, the Fair Market Value of these paintings is between $500 and $600.
