Flag or white portion of flag, in heavy cotton from the early 20th century, of the Principality of Monaco. On the white field there is a shield, supported by two natural armed monks, lozenge pinned with silver and red, with collar of the Order of Saint Charles. Motto in the "Deo Juvante" cartouche. The whole is wrapped in an ermine cloak and surmounted by the royal crown. In fair condition, we would like to point out the presence of a tear in the cotton which does not disfigure the shield, and fraying along the entire external lateral edge, probably the result of cutting the flag. The measurements are approximately 450 x 480 cm
