With his patient seated under a sign reading “TEETH EXTRACTED WITHOUT PAIN,” a dentist asks, “Will you take gas, Sir?” The patient replies, “ER is there any risk eh” [sic]. “No sir,” answers the dentist. “I shall ask you to pay in ADVANCE, TO MAKE SURE.” Titled “Ran No Risks,” this undated illustration reflected the discomfort of a public that by the late 1930s was reading that many dental patients were receiving no oxygen at the start of their nitrous oxide anesthetics. Hand drawn by a cartoonist who signed his work as “AB,” this card is another delightful item in the Wood Library-Museum’s Ben Z. Swanson Collection.
