Though I had already made this so called pennant, it took several google searches to figure out the technical term for it. I was under the impression that this type of banner had a different, more specific name than "triangular banner". But several google searches yielded nothing... But finally I found what I was looking for. Pennant: Etymology: alteration of pendant
1 a : any of various nautical flags tapering usually to a point or swallowtail and used for identification or signaling b : a flag or banner longer in the fly than in the hoist; especially : one that tapers to a point. 2 : a flag emblematic of championship (as in a professional baseball league); also :the championship itself.
My pennant falls into both definitions. First it follows the specifics for the shape of a pennant. Secondly, it is an emblem of the victory that consumerism has achieved over the American people.
