Mondo have a reputation for high quality and artistic posters. Man of Steel being the biggest fish floating around at the moment, it makes perfect sense for Mondo to have posters related to Superman. They have a set of two posters, one by Ken Taylor shows Clark Kent as a boy running in a field with this cape fluttering behind him.
The second poster by Martin Ansin is one heavyweight that puts Superman right into the Man of Steel setting, in a very impressive way. Both posters are available in two editions, the regular and the variant, each being as impressive as the next. Images here show the regulars first, followed by the variants.
