The besst way is to attend the AEE (AVN) show held in Vegas every January.  The stars are there specifically to meet fans and sign autographs.  they usually have 8 x 10's that they sign and give out, but if you want multiples your best bet is to bring your own supply of magazines and/or DVDs and ask her to sign them.

Just don't be piggish and bring dozens of items.  If you want a lot; plan on getting a few signed at a time and come back later for another autograph session.

Also, many of the girls have websites.  Some will sell you autographed items, but many of them will autograph them for free if you send your material to them with a SASE.

Finally, many of the girls have Fan Clubs and will often send you autographs when you join.

In addition to AVN in Las Vegas, there Erotica LA in June.  That's if you don't mind going to LA.  Smaller scale than AVN Expo but still a good time and quite a few girls signing.  On the plus side, they sell DVD's for cheap there.

What do you do with an adult star autograph? I mean you can't really post it in your office or home..

I remember at LA Erotica Amber Lynn gave me autograph photo..I was not too excited about it but I did not want to be rude..Than as I was walking way she says "Hold on that will be $10"..It was an awkward situation so I just gave her the money..Figure she needed it more than me..

Once she got out of my sight I just threw it away..
