Expertise:  Victoria Beckham (Posh Spice.) I can answer things about her books, music, fashion, ad campaigns, and identify most pictures with a location and sometimes an exact date.

Experience in the area
I've been a fan for more than ten years, and along with a friend I run a closed-to-the-public, non-profit, photo archive where we document when and where pictures were taken.

Education/Credentials
