Hehe,I knew what you meant.
My first comment was about 'poster with errors' in general.If it's a popular title with an error,it's getting collected.If it's an unpopular title with an error but the artwork is cool,it's getting collected.So,yeah,if it has an error and it's cool,we want it.
If it's crappy in all arenas it gets ignored.
My second comment was to the 'genre' aspect.I don't anyone but there could be someone that collects them specifically.
