The status of this piece has been uncertain since its earliest appearances. Adams and Woodin considered it a pattern AW334 while Judd / Breen considered it a regular issue. An article in the ANA Centennial Anthology by Michael Hodder, John J. Ford Jr. and P. Scott Rubin describe it as a piece de caprice.
