Bill Gates completed his fourth reddit AMA (ask me anything) yesterday; it’s worth a read if you any interest in the thoughts and opinions of the world’s richest person.

As part of the validation process, AMA participants are asked to verify themselves, typically by posting a picture or message on another verified account such as Twitter or Facebook.

In Gates’ case, his verification photo was the recreation you see above. The original was taken 43 years ago in 1973 when Gates was still in high school; the attention to detail is pretty awesome.

Be sure to check out Bill and Melinda’s 8th Annual Gates Letter, always an interesting read.
