Vespa
Somehow, we have three of these lenticular entries. How did that happen? They are unattributed and we call the motorcycle a Vespa because we know that’s what it is, though there is no caption. Two were mailed from Netherlands with stamp and partial postmark (Grades: 1, $6) and the other was not postally used but has a message and a sticker on the reverse (Grade: 4, $2).
