Vintage instructions for making a smoker's influenza mask

"It's all very well to use an influenza mask. But what if you want to smoke? Edward T. Duncan has supplied the answer. First, buy two-corn plasters at the drugstore. You may not see the relationship between a corn plaster and the influenza. Wait a minute. Hasn't the plaster an opening for a corn? Well, that whole can be made to fit a cigar or a cigarette."
