Atari logo permission for use

[Cronos]

I want to make a T-shirt for STNICCC 2015. I've got a lovely picture but, obviously, there's an Atari logo in it.
I can't use it on a website like spreadshirt.co.uk for fear of trademark infringement (not my fear, their legal department's fear). I need permission from the people who have the right to the logo. Does anyone here know where such permission might be acquired?

You might just try sending an email to pr@atari.com in the first instance.
