This image of a leaf is believed to be the world's first photograph. It is attributed to Henry Fox Talbot who is credited for making the first photo back in 1830s. However some belive that it may have been made 30 years earlier in the late 18 century.

This photo was created by putting a leaf on light-sensitive paper and then it was exposed to the sun. This photo was about to be sold on an auction for about $100,000 -$150,000 but it was withdrawn for futher investingation.
