Your auction listing is important to us

To obtain maximum results we believe that our company has an obligation to our consignors to:

Personally catalog items with accuracy and communicate the beauty of your item
Good photography that allows your item to shine!
Advertising the catalog to the world. We use Invaluable, local newspapers, trade publications as appropriate, communication emails to past bidders at the auction, and social media targeted for the items in the sale.
Previews, both individually and an “open house” at the venue so potential buyers can examine the items.
