It's Ficus lyrata (commonly: fiddle-leaf fig). The spoiled foliage is not a disease and is almost certainly the result of over-watering and an accompanying malady called oedema. Oedema is a physiological disorder that can affect all plants. It occurs when the plant takes up more water than it can rid itself of via the process of transpiration. In afflicted plants, internal water pressure (turgidity) can become so high that some leaf cells rupture or cell contents leak into inter-cellular spaces in leaf tissue. Oedema is most often driven by excessive water retention in the soil, but cool temperatures, high humidity levels, low light conditions, or partial defoliation can individually or collectively be additional contributors, as can anything else that slows transpiration. As well, nutritional deficiencies of Ca and Mg are known contributors to the malady. Symptoms vary by plant, but can include wet or weepy areas on the foliage, blisters that turn from white or tan to dark brown or black, then gradually turn corky/ scaly/ ridged, and wart-like or gall-like bumpy growth.

I'd say Edwardian ish. 1900-1910 roughly. The Edwardians were trying to shed the over elaborate turnings and high style of the Victorian era and went for squarer geometrical designs which led to the Art Deco period.

I'm in Wisconsin. Thank you.
