This is a lovely antique postcard from 1910 wishing a lucky recipient a Happy Birthday. And, it's purple! My favorite color ;-) I've offered three different compositions of the image: the original, without the greeting, and just the illustration, also without the greeting.
The anchor in the illustration is very interesting. I did a little research and found that the anchor symbolizes both hope and stability. It's used in Christianity to symbolize a hope in Christ and in the secular world to symbolize both hope and stability. I often see the anchor on antique ephemera, especially postcard greetings, and I think it was used as a symbol for hope for the future as is used in birthday greetings. I'll never look at anchors the same way again! Perhaps this will give you some inspiration when using this image.
