After some query and conversation, Bleeding Cool has identified that the copy of Action Comics #1 owned and displayed as part of the Impossible Collection (DC Chapter), to be exhibited for the first time tomorrow night in London, is the 9.0 CGC edition bought in 2014 by Metropolis Comics for $3,207,852.
As previously reported, The Impossible Collection is a body of classic comic books collated by its owner over 16 years and includes full runs of the earliest superhero comic books.
I will be attending after tomorrow's screening of Batman V Superman in London – and get the feeling there will be some familiar faces at the event.
I know I like to grab swag at comics events, but I doubt I'll be able to walk out with this….
