Two enchanting watercolors from the 19th century with identification

These two watercolors are from the 18th century. Both are in an old frame. There is a signature on each picture, which designates both the name of the artist and the city from which the pictures come. The pure image size is 21 cm x 15 cm. With frame, the pictures are 33 cm x 27 cm. These are very nice old watercolors. The old suspension with nails and leather loop alone are worth seeing. The price is for the pair.
