@BumpusHounds785,
Shepard Fairey comes to mind.
This is a popular style. The non-authorized Donald Duck is interesting. Sort of Banksy-ish, too. So I wouldn't expect any poster sales without the Disney lawyers writing a cease and desist letter.
Not in my art knowledge/expertise but something I would go to a gallery to look at. And it does look vaguely familiar. A little research should nail it down pretty quickly.
Here's a good starting point. Start searching him and you will find clues to other possibilities. I think he is a good candidate.
Lives in: Chongqing
Chen Zanxi (b. 1982) was born in Panzhihua, Sichuan Province, completing his undergraduate education at the Sichuan Fine Arts Institute in 2005, and post-graduate study at the same institute in 2008. His work juxtaposes the icons of socialist and capitalist culture, such as the Sugar-Coated Bullet series, in which proletariats march past Colonel Sanders in the place of Mao Zedong, or Marilyn Monroe and a pistol-bearing female soldier act out a scene from “The Red Detachment of Women.” Although young, Chen Zanxi is already concerned issues of China's past, exploring how it informs an anomalous present. Recent works have drawn from more operatic sources, emphasizing the theatricality of history, such as paintings based on revolutionary operas with its characters posed in a press release-ready tableau of emotion and drive. In his works derived from China's red past, Chen Zanxi wonders if the present has become “an embarrassing pink,” its revolutionary zeal diluted by the changes of the last few decades.
