On ebay, I found this bottle of Clark's Cordial. Apparently Clark's Cordial was a brand of the Lash's Bitters Company, but unfortunately this is about all I know about Clark's (The label doesnt specify ingredients, but it does say it was non alcoholic). The bottle was produced from 1911-1920* by Owen's Glass Company in Toledo Ohio. I am surprised I got it still sealed, full and with most of the label intact for $45. As much as I'd wish to display it, I keep it in an opaque box to avoid damage to the label's colors.
*I got these numbers from the fact that the bottle mark is an "O in a square" which was used by Owens Glass from 1911-1929. 1920 was from the fact that the bottle uses "Lash's Bitters Co.", which was switched in 1920 to "Lash's Products Co." to avoid any connotation with alcohol due to Prohibition.
