Where can I find some nice stamp exhibitions?

Might anyone know where I can see some great stamp collections?

I agree. It is tough to find collections to see without going to conventions (and there you can only see dealers' collections. My brother does coins, and he uses Collectica.com religiously. I know they have a Stamps section on there as well.

There are thousands of website relating to stamp collecting; I've got quite a few in my own favorites listing on my PC. As a starting point, in the Chicago areal alone there are several large yearly stamp exhibitions (not just dealer bourses). Find a stamp club near you and take it from there; they'll be able to let you know what shows are near you. To find a list of local clubs, go to www.stamps.org and go to the clubs link on the left, then local clubs, then look for your state.

I run several stamp websites myself (and am also the editor of a local stamp club newsletter here in Dallas); all newsletter are free for download even if you're not a member:
