This vintage matchbook cover advertises Oasis Filter Cigarettes, a menthol cigarette brand, and features the distributor Dosean & Son of Jaffrey, New Hampshire. Dating from the 1970s, it showcases a vibrant green and tan design with bold 'Oasis' branding and slogans like 'Freshest Taste!' and 'Best Filter'. The cover is in good condition with some minor wear and soiling consistent with age, and it includes the 'Close Cover Before Striking' safety warning. Matches are absent, and the striker appears unused.
