This expressionless "smiley" button is a response to the iconic image of a smiley face paired with the phrase "Have a Nice Day" that defined the 70s.
It was known that Harvey Ball, a graphic artist and ad man from Massachusetts created the yellow smiley face in the 50s. In the early 1970s, brothers Bernard and Murray Spain, owners of two Hallmark card shops in Philadelphia appropriated the image by adding the the slogan “Have a Happy Day” to the smile. The Spain brothers copyrighted the revised mark in 1971 and produced their own novelty items shortly after.
