Some large letter postcard collectors made checklists that they shared with other collectors. Some of these checklists were published or in the internet age, posted on the web. Below are some of the notable checklists we have found.
1949 - Thomas F. Spock
1955 - Elsie M. Hawbecker
1987 - Bob Murphy - Later on, updated second and third editions were made
~2005 - Jeff Vorzimmer - Curt Teich and Tichnor checklists, occasionally revised
