I know there are several National Threads out there, but I didn't see any that focused on autographs, so I thought I would share my observations
So I flew out to Chicago for a day trip Saturday, crowds were actually much lower than I expected and saw last year at Cleveland.
1)  If you wanted a big name vintage player (Ruth, Mathewson, Cobb)-there were plenty of dealers out there.  Since this wasn't my focus, I didn't spend much time at their tables.
2)  If you wanted the vintage tough HOF stuff-there were about 3-5 dealers I could find (Kevin Keating, Joshua Tree, Rhys-Prewarsports) with Kevin having the vastest selection.
3)  There were few, if any, bargains.  The dealers know what they have is rare and even though business didn't seem that brisk-the dealers did not appear to give great deals just to break even for the show expenses.  That being said:
4)  The dealers I spoke with could not have been any nicer.  I spent hours with Rhys, Kevin Keating and Joshua Tree as was delighted to make purchases from all three.  
5)  NO-ONE I spoke with looked forward to going to Atlantic City next year.
Anyone else go?  Would love to read other's opinions/observations.  FYI-Here is the nicest piece I saw the entire show, which Kevin had-a team signed 1896? Boston Beaneaters piece w/Selee, Collins, Duffy, Nichols and Hamilton.  The asking price was $100K.  I apologize for the glare.
