The Diane McKenzie Hospital Postcard Collection consists of hundreds of hospital postcards from the United States and throughout the world. A small number of pharmacies are also represented.
A former librarian at the Health Sciences Library, Diane McKenzie donated her collection of hospital postcards upon her retirement. Several other medical librarians have contributed to this still-growing collection over the years.
Assigning a date to a postcard can be a challenge when no date was stamped onto it at the post office from which it was mailed. However, it is possible to narrow down a postcard's publication date to a particular time period. You can do your own sleuthing with the information on the North Carolina Collection's How To Date Postcards page.
