From Sergio Lugo
The latest of these is now held in the February time period. It has experienced a huge and improved face lift under the direction of Paul Domenici and Gary Withrow and the aid and assistance of many volunteers. Individual lots are now described and illustrated with color scans of the contents (some couldn't be done completely - roughly 90 are cover lots, that only illustrate three covers per lot for the thousands of covers contained in the 90 lots). Contents of all other lots are well illustrated (doesn't look like they can be magnified) and described, with VERY REASONABLE starting bid prices.
