What an awesome idea.... There is a website where you can get the paper from the day they were born... DP's cousin got one for MIL's 60th, it comes in like a big album thing.. let me see if i can get the details.. you might just be able to get the front cover or a page that would interest her!
... ZF would you believe my DP got me one for my 40th birthday and i got one for Dad on his 70th, it's was pricey about $180 (that's a newspaper of your request if avaialble, i got the Melb herald newspaper, of the day you where born in unused prestige condition in a beautiful binded folder for life keeping) ... it's an absolutely awesome gift isn't it ZF

Nai would you believe i saw a kids book annual 1971 in an OP shop today, if i see it there next time i go again i'm gonna get it for you as Miss G might like to read it (not sure what was in it or what condition it was in, might have been TV characters or something as the front cover character looked familiar - it was a yellow (??) dog with long shaggy hair and button eyes !! ... Nai harr harr i had a matchbox combi my Nan bought me in 1970, i remember it was silver
