The back, neck, and sides are made from solid mahogany. The center stripe matches the inlay on the face. This guitar appears to have been oversprayed with lacquer sometime in the distant past. As with the other OS mentioned earliar, the peg head is faced with rosewood and sports the 5-pointed star inlay typical of OS manufactured Supertones. These tuners are modern replacements, as is the nut. The ebony fingerboard is also bound.
Although the most common Supertone brand guitars were made for Sears Roebuck by the Harmony Co. (and sometimes Regal) of Chicago, IL, it is well known that the higher end instruments were almost exclusively made by Oscar Schmidt, of Jersey City, NJ. This one can be dated precisely to May 2, 1925, because it is stamped on the label, right under the Supertone brand name.
