1965, Cyn wrote this postcard to Julian & Dot (the housekeeper) when John & her were away in Austria (the Beatles some scenes for Help! there). 

Note that is it addressed to "Master Julian Lennon" lol.

An original receipt of clothes bought by Cynthia in the mid-60s.

This is from Dot Jarlett's collection (who was the Lennons' housekeeper).

Thought it was pretty cool ! ^^
