Dear Laura,

Thank you for your request. Thank you for the additional images and your patience. The apprised object is a pair of paintings made in oil on canvas with the measurements of 22 1/2" X 33" each. It depicts a landscape and is signed with J. Anderson and dated with 1900. Sadly for this artist, no further information of the biography are mentioned in auction records or similar databases.
This piece is in medium condition but there are no serious damages visible.
An estimation would be between 150 to 300 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
