I recently hosted an open house in Alton, Illinois that was one of the most educational that I've every done. The homeowner had photos and small cards with information placed all over the house for visitors to familiarize themselves with the history of the house.
The history not only included how and when updates were made, but also included framed photos in strategically placed areas of the original family that built the home in the early 1900's with historical information on the family.
The information answered many of the questions for my visitors who became intrigued at reading each and every card on display. I picked up two good leads when I was able to add information that I was familiary with for the area surrounding the house.
As a former history teacher and a genealogy buff, I was intrigued by all of the information the owners were able to supply, and as with all genealogy, I was able to associate the house with a time period in historical events of our city.
Just a thought!
