Blind Faith
Before the band had a name, they were planning their first album. They had asked photographer Bob Seidemann to create it for them.
Bob came up with a concept which included an object representing the tree of knowledge (a space ship) and something representing the tree of life (a naked prepubescent girl).
When traveling the London Underground, he spotted the perfect model. He asked her and her parents' permission and all agreed. But later she backed out and convinced her sister to do it instead. She was promised a horse in return - which she never received.
The cover was a success, and Bob titled the work "Blind Faith". Eric Clapton loved the title so much, he adopted it for the name of the band.
