This is the design for two sister torpedo boats, created by Yarrow & Co. (Poplar, East London) in 1887 for the Spanish government. The torpedo boat was not a terribly-new idea by this point, the first "modern" version of the craft built in 1875 (HMS Lightning), with earlier versions launched during the U.S. Civil War (like the CSS David). The designs shown here are for the Azor and the Halcon,135' of attack-capacity (with 1600 hp), certainly making them high consideration for the folks on the receiving end, leading to the development of the torpedo boast destroyers to protect the big battleships and hunt the torpedo boats, and idea that would lead to "destroyers". In any event, I found the image attractive and interesting, and thought I'd share it:
