There are very few shows. The International Cue Collectors Show is a great experience. It's once a year and I highly recommend it. To exhibit and participate, it is by invitation. This year it's the weekend of Oct. 30th at the Ritz Carlton in Sarasota Florida. The public viewing is Saturday October 30th from 1 p.m. - 6 p.m. $10 admission.
If you have a nice collection and wish to display, there is a whole weekend of activities and workshops, and some of the world's top collectors and cue maker's will attend and exhibit. Contact Will Prout here on AZ Billiards, "Ibuycues". There will literally be millions of dollars worth of cues on display. If you are a cue nut, it's worth the weekend trip, believe me.
