|   | Cardboard sign, a vintage Pepsi advertisement for a promotional offer featuring DC Comics superhero glasses.
    The promotion, which appears to be from 1977, offered a "Superglass" with the purchase of a medium-sized Pepsi for 59 cents. 
The glasses feature various DC Comics characters, including Superman, Batman, and Wonder Woman. 
These glasses are part of a collectible series from the 1970s and are sometimes referred to as "Pepsi Super Series" or "Pepsi Superglass". 
Similar promotions for superhero glasses were also run by other companies, such as Taco Bell, in the same era. |
