This seat seems to be in fashion in the hill town of Montepulciano in the Siena region. We went there to "mangiare". The town is situated on a mountain ridge and you enter through a medieval gate. The you walk and walk uphill until you reach the piazza. Very nice!
The blue Vespa seems to be a 50 Special. The green should be a PK, vero?
I can't read the make of the saddle. Photos by telephone so the quality is not at it best. The photo of the green Vespa was taken at 21.30.
