The short story is, my aunt 45yo, was diagnosed terminally ill just over 2 years ago, a recent scan, has show she now has months left 
She is guardian to her 4yo grandson, and has been since his birth
Her mother died very young again with cancer, and my aunt was placed into care, where she was sexually abused the whole time there
She started a new chemo 3 weeks ago, and woke up the morning before last and had lost every single bit of her hair
She battled breast cancer in 2003, but it come back some years later in her bones 
She really has had a really terrible life, I will not go to much into detail, its not a nice read
Its her birthday July 7th, its very likely it will be her last birthday.
She is a massive F1 fan, in particular the F1 driver Heikki Kovalainen [so much that her grandsons middle name is Kovalainen]
Im desperate to get her a signed birthday card from Heikki Kovalainen
Ive left messages on his FB, and Twitter page, and heard nothing back
In the messages I have offered to pay for the card/postage
Has anyone got any advice on how to get this card for her
I have no idea of any contacts/address to get the right people to read IYSWIM?
