One goal of collecting is to dig out those special 'objects' from among the common; it's both fun and a challenge. These items don't need to cost a great deal as they, like their museum counterparts, are simply difficult to find and once found, revered. These are a few of the (philatelic) 'objects' that contribute to great collections. Thanks to our contributors for their graphic scans. - Asterisks indicate the most recent entries for each area.
