Tver, imperial traveling palac

The palace with two pavilions was built in 1764-1766 in the style of classicism with baroque elements designed by P.R. Nikitin, and was intended for the rest of the imperial family members on the way from St. Petersburg to Moscow, from which it got its name.
This right pavilion is crowned with a golden star whose rays are directed in different directions. Nowhere else did I see this.
The work is inserted in a white wooden frame.
The size in the frame is 46x36 cm.
