Best Auction options for Ruth Eclipse Ad Back on strip

[thesoutherntraders]

After several messages and offers I'm starting to think I may have the only 1933 Eclipse Babe Ruth ad back known to exist. On top of that it is still on the strip. If I am posting this in the wrong forum I apologize but I was wondering what auction house everyone thought would be the best option to sell such a rare card? I am not in a huge hurry to sell it so if anyone knows of any big auctions coming up please let me know!
Thanks!
