Massimo Vignelli is very sick. The legendary graphic designer — his works include the 1970s-era NYC subway map and branding for companies like American Airlines and Bloomingdales — is “spending his last days at home,” according to Creative Reviewand his son Luca is asking fans of Massimo’s work to send him letters.

Says Michael Bierut of the design firm Pentagram:

Luca said that Massimo would be thrilled to get notes of good wishes from people whom he’s touched or influenced – whether personally or remotely – over the years. Luca has visions of huge mail bags full of letters. I know that one of Massimo’s biggest fantasies has been to attend his own funeral. This will be the next best thing. Pass the word.
