Please don’t reply wtih Ebay or craigslist!! I am looking for a reputable buyer on the internet or in a local store. I live in the SF Bay Area, CA. I have about 20 posters, some well known, Janis Joplin, The Doors, etc. others not so well known. The more high profile ones are "Bill Graham Presents" done by the legendary Randy Tuten in the 60’s. I am not familiar with the sixties music poster collecting community, so I don’t know if I need to have them professionally appraised and authenticated before selling them. Would this get me more money for them in the long run??

I have to do a project for geophysical science and the topic is finding an interest/hobby I have and say how the scientific principles of Physics that apply to the interest/hobby. I chose listening to music (I’m putting on the poster "Listening To The Music Of The Doors") and I don’t know which principles of Physics are applied to this and how. Can someone help me?
I forgot to add that this is due on Tuesday, April 13.

My little brohter always gets the royal treatment. He is 3.5 years younger than me, and he always gets treated better than me. His room Has an air hockey table, two room closet, giant posters, sport style locker shelves on his walls, every sport collectible you can imagine, a TV that the Patriots gave him, and nice wall trim, freshly painted walls, and sporty curtains. All I’ve got is a room painted baby blue from twelve years ago, no trim, a big opening in my wall that is being covered by a blanket, only storm windows, a filled in shelf with an un-sanded, un-painted piece of sheet rock, an un-painted closet, a TV that I bought with my own money, hundreds of little tack holes in the walls, and a big one where the door handle is, because there is no door stop. Speaking of doors, mine has chipped paint and tape stuck all over it. My mom asked me to clean my room and also vacuum my brothers room today!

I am redecorating my room, and i want to get some cool music posters for it. I want to pay about 5-7 dollars total for them, but wherever i find them shipping adds about 5 dollars. does anyone know a good place to get them? I want some like: Billy Talent The Doors, Green Day, The Ramones, The White Stripes, The Used, and Blondie
