Recipe?

Came across this while taking a walk. Wonder if there's a record of this on paper in the archives of City Hall?

On another note: the vines on the right are Virginia Creeper. Although it's pretty, this plant grows vociferously and will take over trees, telephone poles and anything else it can get a grip on. We've had personal encounters with this plant in the back yard of our new place. It had nearly smothered a deck and 5 rose bushes, and had spread into other parts of the yard. I think we've gotten rid of most of it by now. We'll see what it does next spring....
