Travels through space with Parseval! (Luftfahrzeug-Gesellschaft m.b.H, 1910) seems fitting for Travel Tuesday.

Parsevals were the rival to Zeppelins, and this pre-WWI piece of business literature gives a unique look at the arms race before the First World War. The catalog records indicate that the donor of this item had actually seen Parseval airships near Hamburg, Germany in 1911. The item is in our National Air and Space Museum Library Special Collections, though you can read the whole thing online.

This is Parseval's Theorem, but a more general form of it. It's called General Parseval's Theorem."
