Nest of Speckled Eggs with Strawberries and Clover, Early 20th Century Trimmed RPPC

I can't resist a photo of a bird's nest, provoking immediate feelings of coming upon a precious and delicate thing--such that I have to get it to a safe place and protect it!  And this nest nestled amidst wild strawberry and clover, with three beautifully speckled eggs inside it (the specking itself a form of camouflage.) So lovely.

4 3/8" x 3 7/16", very good condition. I would not have known it, with matching borders on all sides of the image, but from the reverse it appears to have been trimmed down from an old rppc.
