I've scanned thirty of my dad's old post cards. I'm sure they were all made before 1924, because that's the year his mother died, and some of them are signed by her.
It's a real shame that so many people back then wrote letters and notes with lead pencils, because the writing fades so badly you can't make out a lot of it.
I'm having a problem with AOL pictures when I try to make an album; that's why I stopped with four post cards. Sometimes I'll think it's uploading just fine, then I'll get a message that says, "No pictures were uploaded".
