This website, created by John Veevaert, was one of the first of its kind on the the world wide web.

He wanted the site to continue, for the dealers and for the collectors, because it was all about community for him. His wife, Ronna Veevaert, is excited to continue the auctions in John's memory, with dedicated assistance from Richard Geiger and Luciana Barbosa. We want to make it a great site, with fun auctions for everyone!

Thank you!,

Ronna Veevaert
