A publisher's calendar for Independence Day
Here is an appropriate piece of ephemera for July 4th, Independence Day in America: A 1925 calendar from the American Book Company, which features early meeting places of the legislatures of the original thirteen states. As there are only twelve months to associate with the meeting places, the vignette for the thirteenth state is that of the Pennsylvania State House in Philadelphia, 1776. This is where the Declaration of Independence was adopted on this day 233 years ago. Today it is called Independence Hall. The vignette is printed on the cardboard backdrop that holds the monthly calendars, each with their own vignette.
I've included some interesting history about the Declaration of Independence in a post on Archaeolibris.
Happy Birthday, America!
