💌📬🔘#USPS " #MrZip #USMail" unlocking button #196x "..Mr. Zip, or #Zippy, was based on an original design by #HowardWilcox of the #CunninghamAndWalsh advertising agency. The design was purchased by AT&T and given to the United States Postal Service (then the United States Post Office Department) to encourage the adoption of zip codes by the general public in the early 1960s. AT&T had warned the postal service that the public might be less than cooperative, citing their own difficulties introducing area codes."
