I've selected five images to mark the arrival of the 2026 winter solstice and the following period of astronomical winter, which last through March 20, 2027 (the spring equinox).

Each card includes a caption explaining the image's source, as well as a scannable code linking to a page on the Earthly Book of Hours website. You or your chosen recipient can scan the code to lear more about the image and the natural phenomena it depicts.

I'm still finalizing details, but the cards will be printed on recycled paper and shipped first-class mail within the U.S. from my apartment in Massachusetts.
