Chinese Collage Pictures made with paper, bamboo & Feathers (Characters identified: 松楓 沈陽) We have a set of 3 collages bought from Hong Kongaround the 1970’s.  Do you know who the artist is please?
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.
