Pressburg (or more accurately, Preßburg) is the old name of modern-day Bratislava, the capitol of Slovakia. It’s a few miles to the east of Vienna. The house itself is not — as far as I know — Kempelen’s actual house, but it is based on an actual house in Bratislava.

The plans that von Kempelen has in front of him are for a mobile bed he invented and built for the Empress, who was suffering from smallpox at the time. It was essentially the precursor to a modern hospital bed — it could be raised and lowered, and rolled from room to room, so that Her Majesty could still conduct business during her illness.

The drawing which hangs behind von Kempelen in panel 1 is actually based one of his own, which I found in this biography by Dr. Alice Reininger.
