Advice Needed On Selling Multiple Cinderella Collections

I have a number of significant cinderella collections I need to sell before moving out of the US. There's too much (and too little time) to sell items or small lots on ebay etc. Collections are:

Pre-1940 Air seals - Air shows, clubs, commemorations, semi-officials, 1500+ items WW with particular depth in Germany, France. Also 100s of real photo postcards of pioneer air flight era subjects

Spain seals - exposition, separatist, esparanto 1000+ mostly pre 1920

Spain Civil War - 1500+ both sides all kinds

Stamp shows & exhibitions - 3000+ mostly US mostly pre 1970

Artistamps - 2000+ mostly US, mostly last 30 years

Pictures of stamps on postcards, trading cards - 1000++, Zeiher, language of stamps, etc

All suggestions, experiences appreciated

Thanks

I might be interested on the Spanish cinderellas, if you can send to me scans of them.

50 posts are required before any email exchanges.

RR I was hoping for dealer or auction house advice not offers to buy. That said I've now read the rules more carefully for furture reference

Thanks

Aerodwyer, if you google "cinderella stamp dealer" you will get what you are looking for.

Aerodwyer:

You are fairly close to Portland, OR. You might want to visit the bourse held on the 2nd and 4th Saturday of each month at the Oregon Stamp Society http://oregonstampsociety.org/.

Also, you can look for nearby dealers who might be interested in purchasing the collection by using the Find a Dealer links on the web pages of the National Stamp Dealers Association http://nsdainc.org and the American Stamp Dealers Association https://www.americanstampdealer.com.

When I have had problems with ID of cinderellas, Roger has always been generous with his time.
