An aging James Abbott mural in McCleary, Washington depicts a merchant at the McCleary Eyeball Store
When I was a kid in McCleary I recall you could buy a decent eyeball for only 50 cents, but those darn federal regulations came in with Nixon and before we knew it, eyeballs were no longer obtainable by us normal folk. And another local business went under. My memory tells me blue was more popular than brown.
There was also a McCleary Spleen Store, but I do not believe that has been celebrated as part of a historical mural.
