Awesome idea! I was born 1971 and DP is 1969 so we are fairly close to 1970. Some things that a friend got for DP was a 1969 Boy's Own book, a 1969 tea-towel, a 1969 footy record, a toy VW combi van.... however I'm guessing your firend wouldn't want these

They have some retro barbie dolls in toy shops at the moment although I think the Malibu barbie is 1971. There is a site called gifted memories which sells cd's and dvd's from the year you were born.
