Ep. 54: The Importance of Periodicals

Michael and Charles discuss why periodicals are so important to the hobby, and a couple recently published philatelic articles, including; 1868 Production Grills: Why Size Matters by Rex Dean Bishop and The US 5C of 1847: A New Approach to Impressions and Colors by Scott Trepel. They cover topics such as the enigma of the z grill, why philatelists should care about grills, and new ways to classify stamps based on quality of impression.
