Greetings, Indulge me a little.
I have some nice swag from back in the day as I have owned ReQuests, Summits, and now 15a's.
I would let go of the Bon Jovi T-Shirt that has Great American Band on the Front and the ML Logo on the back with Great American Speakers on the back. I have slippery when wet and living on a prayer is a great song but I am not a big fan of Bon Jovi and could let it go. Also I have just a ML black T-Shirt with just the logo that I always wear. Size Large although washed a couple of times so maybe Medium plus? In any event I would trade for the new Saint Vincent cd .
The illuminated sign I got off eBay way back for under 20 bucks if memory serves. It was in blue when I owned Summits and I changed to white illumination when I got 15a's to match the color. I liked the blue better (Hell I liked the blue line of the Summit better as well) as the 15a's has the fender feeler aspect to me but you can turn em off so there is that.
I also would advise you to use Groupon or search for having images transferred on medial of your choice. I have some metal signs from meme's that struck me and they came out great. You would have a lot of options there.
