Interesting reading recently about how surrealist artist Salvador Dali designed the Chupa Chups logo. The famous lollipop was first made in 1958 and named 'GOL'; envisioning the candy as a ball and the mouth as a net. Sales didn't make much impact.
In 1969 after an ad agency renamed the product 'Chupa Chups', the lollipops founder Enric Bernat was having coffee with his friend Salvador Dali and complained about needing some branding. Salvador immediately starting doodling on a newspaper, the beginnings of the design (unchanged to date) as we know it.
Dali also insisted the design be placed on the top of the lolly so it could also be seen in one piece. The graphic designer in him.
Why did Dali do the project? It was supposed that as art often not the most lucrative of trades, Dali needed the cash. He was nicknamed 'Avida Dollars', an anagram of his name which means 'eager for cash'.
