The following is an overview of the types of postcards we have listed, along with the abbreviations we use throughout our site:
PE - Pioneer Era (1893 - 1898)
This era began at the Columbian Exposition in Chicago in May, 1893. All cards of this era have undivided backs, and many will have the words, "Souvenir of…" or "Greetings from…" on the card. Many postcards of this era are multiple view cards.

UB - Undivided Back Era (1901 - 1907)
