In a letter dated June 15, 1949, Nels Garden wrote: "we have no immediate application of them, inasmuch as we find the use of our Kum-Kleen hazard-signifying labels quite satisfactory, especially in their ease of removal during decontamination."  Garden was referring to the Kum-Kleen radiation warning  stickers produced by the Avery Adhesive Label Corporation.
