The history of postcards is part of the cultural history of the United States. Especially after 1900, "the postcard was wildly successful both as correspondence and collectible" and thus postcards are valuable sources for cultural historians as both a form of epistolary literature and for the bank of cultural imagery included in the postcard illustrations reflecting historic popular culture norms and tropes.[1] Postcards are also valuable resources for scholars of architectural and regional history.[2]
