Large format photo with MVSN Officer and civilians, the uniform dates back to the late 1920s/early 1930s; the photo was taken in the churchyard. There is an MVSN Officer wearing an M32 eagle-head dagger and an Officer with an Alpine hat with a very strange insignia and insignia... he could be an Officer of the Army of the Republic of San Marino.
