Corson has no information on this publisher, and I have
only ever seen this one lovely card from 1908.
It makes an obvious pun on leap frog and Leap Year although the
verse and drawing have little connection.
As a card with appeal to both Leap Year and frog collectors, it tends to
go for a higher price.
If
you have other images of A. L. V. Leap Year cards, please
contact me.
