A card saying Happy Birthday, many happy returns of the day. To sit in the trees and sing with the birds is a pretty concept. The little girl's balance is as good as the birds. Today was the birthday of the poet Robert Herrick whose lines seemed appropriate to head this post.
The card was sent in 1919 from the village of Rothrist-dorf in the German speaking canton of Aargau, Switzerland with a couple of their William Tell definitives first issued in 1910. It is sent to Helene from "your sister Lydie". Lovely writing but don't know what the rest says, it starts with Meine (my); possibly its a loving greeting.
