I cant see a signature , but it could be under the frame as it is clearly labelled with the title and date it was actually painted. It is I believe a bridge over the river Seyhan  , in Adana, Turkey. Although the label on the back says Serham, it was painted 26th March 1925. The size of the actual watercolour is 22cm by 10cm, the frame size is 45cm by 31cm. This can be posted in its frame, but i will reduce the cost a little if you dont require the frame. The picture is glazed, and pictures taken outside, so you may see some reflections on the glass
