The Verge Historic Painting: Maslenitsa by Boris Kustodiev, 1919. This amazing painting depicts the Russian winter holiday festival just before Lent.
Research rabbit holes and drunk archaeologists: The making of my KV35 Egyptian tomb video. Sometimes "doing history" is perfectly infuriating. Even then, it's kind of fun.
Interiors: Garden Court, Palace Hotel, San Francisco. This is one of the central features of the grand Edwardian-era hotel, completed in 1909.
