Yep to all of that...I always look at the messages on postcards. I purchased a lot of postcards at an estate sale a year or so back and noticed that all of them (about 25-30) were signed by the same man who seemed to be doing a lot of traveling and sending postcards home to his wife and kids...I also found it odd that he was signing his full name to them. I googled his name "Charles M. Sheldon" and found that he was the originator of the phrase "What would Jesus do?". That just made the small collection that much more interesting to me.
And it's definitely the "famous" Charles M. Sheldon...cards were sent to Topeka, and his daughter was named Merriam which was also his wife's maiden name.
