Another interesting thing about the poster I'm searching for (if you've read my rant on that page) is the fact that it's a posed photo, not a performance shot.
It's basically a poster of Alex standing and grinning, holding his brand new (cherry) double-neck guitar, with hair going almost down to his waist (the longest you've ever seen it, I guarantee). I'm quite sure that the photo would have been taken very soon after he purchased the guitar.
Step 1 for me will be finding another Rush fan who actually remembers having seen this poster, and step 2 will be actually finding an image of it. Step 3 is to actually get a copy of it.
At this point, I'm actually beginning to lean towards the notion that the absence of this poster represents a conspiracy promulgated by Alex Lifeson himself. It's as if Alex doesn't like the poster or something and wants it to be erased from history.
If you ever see this image, you will completely understand why its disappearance has been driving me crazy for the last 20 years. It's simply to cool for words to describe.
Yes, I'm an unapologetic Rush fanboy...
