I just got this a few months ago on Amazon, and was reminded how great it was while doing some spring cleaning this weekend. Not too much to say about it, but I thought I would recommend it. The seller offers it both plain and with several frame options. If you have the time, I got mine unframed and took a couple minutes to put it in a $30 frame from Target.
There are a few similar posters if you like the old Comic book look.
