Hello Brian,
Glad to have you here, and welcome to the addiction. Wait a couple of months, chat with us a little, and you'll be hooked. And once you're hooked, there is no turning back. Ask Mel, who started collecting modern posters about a year ago and quickly amassed more than 1,000 pieces, some of them quite old and rare. Ask his banker, I'm sure he's got something to say about it.
And have fun browsing.
