Victorian Valentine's Day Greeting Card with Cherubs in Birdhouse

The card seems to be celebrating romantic love, yet the image shows three cherubs who have apparently formed a jazz ensemble inside and around a wooden birdhouse nailed to a flowering tree. One cherub blows a trumpet inside the house, another perches on the roof playing what appears to be a saxophone, and a third dangles below on a branch with his own horn — a full three-piece band, none of whom appear to have been invited. The horseshoe nailed to the front of the birdhouse raises urgent questions about what kind of luck these cherubs need exactly, and the two floating red hearts scattered around the composition feel like management trying desperately to remind you this is, in fact, a Valentine's card and not a surrealist painting about children who live in trees.
