Vintage postcards for the 4th of July. These are a little different so they are of particular interest. The first one uses a depiction of a Native American to celebrate the holiday, which seems curious because Native American issues are rarely considered in discussing the English colonists' rebellion against the crown. The intent seems to be the preservation of the legacy of the original land, but we all know how that turned out for the Native Americans.
As far as the history of the Ridge goes, there was a strong historic presence of Native Americans in the area, especially along the Calumet River. Archaeological excavations are currently going on in local forest preserves. But the Treaty of Chicago in 1833 led to the withdrawal of the remaining Potowatomi to west of the Mississippi River.
The second postcard is actually for July 5, the day after the holiday. It shows a child and pet recovering from fire cracker injuries. While this might have had a humorous intent, it also serves as a warning to be very careful with home fireworks displays.
