The original Apple Computer logo (pic 1), depicting Isaac Newton sitting below an apple tree. The logo was designed by Apple co-founder Ronald Wayne. This logo was only used for one year (1976-77).
In 1977 it was replaced by the "rainbow" logo (pic 2), which was in use for 21 years. This logo, famously, became the subject of a long-running trademark dispute with the Beatles who also used an apple logo. The lawsuit was settled in 2007.
Ronald Wayne was only with Apple Computer for twelve days, whereupon he sold his 10% share, for $800, back to Jobs & Wozniak.
A year after this he accepted another $1,500 to renounce any future claim on the company.
When you consider the value of Apple Inc. now, that must be considered as one of the worst ever business deals.
