This next site NFFC is the National Fantasy Fan Club. Its all Disney and has been around more than 20 years. If you join (for about $12.) you get info and access to many sellers/buyers..strictly Disneyana. They have 1 yearly convention, in July @ DL. It was a great convention...I went last year. Also..2-3 times a year, Disney sales conventions across the country.

Well...that should keep you busy...hope I've helped??
Are you looking for something specific?? I ask because I have been a cel collector for 30+ yrs. I had 16 original production cels + original "Fantasia" pencil sketches.....which I had auctioned off by Sotheby's in 2003.
I still have a few LE's (25/275 Snow White, Lady/Tramp, MM etc) also...serigraphs and sericels...in their original packaging..never opened, never hung....of course with certified documentation......For Sale.
You see...I have retired..and needed to downsize quite a bit..with no room to hang all my wonderful memories. My DH has passed away and we had no children. Yes..they were difficult to part with, but, Charlie was certainly my true loss...and now this is only stuff.
Good Luck!!
Dont hesitate to pm me with any questions...
