Not on a stamp, in a Vespa 400

Photo from the Piaggio archive.

Neither English nor Italian is my first language, as you all have noticed. So, when the news about a stamp with Corradino D'Ascanio (1891-1981)  came, I misunderstood. Stamp is both postage stamp and seal or punch. To commemorate the exhibition at the Piaggio Museum in Pontedera regarding "ingegnere" D'Ascanio, there was a seal/punch just for 22th of December.
Sorry to say, no postage stamp!
Here instead is a photo of the genius, in a Vespa 400 with his grand children!
