In 1959, I spent the summer up in Gladwin Michigan with my aunt and uncle, who lived in a little home like this...well actually theirs looked brand new, and the inside was adorable, the woman could turn anything into a magazine photo! I think it was an Airstream. I'm probably wrong about this one, but I think it's from the late 50's.
