Justacargal (Tere) went to the Peterson Museum and posted several galleries, this one shocked me, there was an Autoped at the museum!

 

 The Autoped was used by the US Post Office delivery service in 1917 http://justacarguy.blogspot.com/2008/11/scooter-was-born-about-90-years-ago.html , as this photo from Shorpy shows

But those are just a couple photos of just the Autoped, from Tere's gallery of the scooter exhibition, so make her day with lots of visits to her site http://justacargal.blogspot.com/2011/11/peterson-museum-fall-2011-scooters.html , and you'll have my thanks for making her happy!
