Here's mine on my Kenmore 90-Series, from the '1990's':
I remember reading the inner-lid on my late-grandma's General Electric Filter-Flo (Left-Side Opening; most-likely bought at her local K-Mart store, or some Mom & Pop dealer, where she'd probably bought her Kelvinators from--although I remember her saying "Federal's") stating: "To Prevent Personal Injury--"...
In order from the working collection: 1966 Inglis (bilingue, bien sûr!), 1966 Blackstone; from the 'pile waiting for my attention in the garage', the 1957 TOL GE FilterFlo.
Amazingly, I have no photo of the lid on the '59 Frigidaire Custom Imperial.... For shame!
