Why a Wico artwork gallery?  Wico was a major player in the arcade industry, producing or distributing a broad range of products, including our favorite classic joysticks and spring loaded buttons.  At one point, they struck a distribution deal with Willis Industries for reproduction overlays and other products. You can find Willis products in some of their catalogs (see below).  This relationship ended in a lawsuit (re-post coming soon) and a termination of the business partnership.  Shortly afterwards, Wico started producing their own reproduction control panel overlays.  I’m not sure if they were officially licensed, but they are easily recognized by either the Wico name or the part number which seems to always start with a 26.  The one thing worth noticing is the quality of the artwork.  Even a Willis fan-boy like myself can’t argue that the art quality is better.  I only have a handful of these, but I suspect there are many more, some potentially un-marked.  So if you’ve seen one in person or in a catalog, let me know!
