The prequels tend to be forgotten in the current world of geek/fan fashion, an injustice I rail against constantly.
However, someone making these Hot Topic socks decided to use images of a clonetrooper, Artoo and his jet-propulsion rockets, and possibly a lightsaber-wielding Yoda (hard to tell from the picture). Very sneaky, but SWPAS approves. Now about some Maul, Jar Jar, Grievous, Anakin, Obi-Wan, Padme, etc. in the future ;)?
