Recommend an Auction House?

[Diane Merkel]

From a website visitor:

I am trying to locate the names of auction houses that are interested in civil war and post-war photographs. I am familiar with Cowan's but am seaching for additional ones. Would you be able to recommend any? Thanks for your help.

Has anyone had experience with an auction house from the seller's perspective? Any recommendations?

Heritage.com dealt with the recent sale of GAC's guidon. They also sell Indian items.

James D. Julia handled the sale of those recent Custer letters, with plenty of photos as well among the lots. And I think Alexander Autographs also deal with photos as well as letters.

But I have no personal experience of either, whether as buyer or seller.
