Otto Hoyer worked in Paris with Eugene Sartory between 1911 and 1913 and used the “ Otto Hoyer Pariser” stamp on his finest bows as with this exceptional viola bow. Before going to Paris Otto Hoyer worked with his father Ernst August Hoyer. The frog has a “see-through” lens (known as a Stanhope lens) with an image of the maker inside. This viola bow is a superb example of this master’s best work and has excellent playing qualities, quick, responsive and relatively light.
