Ostropa souvenir sheet with additional franking on foreign countries registered cover to Kuopio / Finland with reverse arrival stamp. As 20 Gr. cover sends and with 55 Pf. franked, what then correctly franked was. The souvenir sheet point at in the "o" and "p" of the watermark slight breaches on, is but otherwise entirely intact. The adhesive traces are by of this issue as normal to look at. As correctly franked international franking rare! Michel .
