Chinese Collage Pictures made with paper, bamboo & Feathers (Characters identified: 松楓 沈陽)
Just so that there's no confusion about the character shape in the seal, which is 「陽」 and not 「揚」. See the third shape below:

商甲前5.42.5合集14855西周金農卣集成5424西周金虢季子白盤集成10173秦簡法57睡虎地秦簡今楷　

The left-hand-side component of the character is 「阜・阝」 rather than 「手・扌」. There is a fair amount of fading around the middle of the character.
