So I was looking over my key 1/6 interests.
Batman was created in 1939. I chose his 1992 Tim Burton incarnation (up for pre-order).
24 years after Batman, Stan Lee gave us Iron Man and The Amazing Spider-Man. I chose their 2010 and 2014 film versions, respectively.
Bruce Lee began his feature film career in 1971; I have his 1973 Enter The Dragon appearance.
1977 gave us Star Wars, with '77 SW and '80 ESB represented in my collection. This last one is problematic, as I have a couple of figures I'd like to add but need to make brutal edits to keep the population down. But anyway...so far that's 41 years of pop culture history in six 1/6 scale figures. Tight.
