250 254 Park Place Flower/Window Containers

Does anyone know where I can get 1/4 circle shaped window containers like they have on the first floors of 250 & 254 Park Place? I have pot bellied window bars and I'd like my containers to contour with the bars. Preferably in wood that doesn't need sealing. Locally made, stores or online ordering is fine. Thanks.

Have you tried asking people who live there?

Yup. I never see the lights on and there's nowhere to leave a note.
