A small correction
Michele, a sharp-eyed user of The Philosateleian, wrote earlier this week asking where to find a space for a 3¢ Eastern Bluebird stamp. In the process of tracking that down for her, I discovered a typo on one of the pages for stamps issued in 1990 and thereafter. Oops. Thanks, Michele!
The typo has now been corrected, and you can download the updated page for your collection.
