Here are two thoughts:
In the current issues of McCall's, there is a general notice that gives permission to use any pattern for public display. I think it's on one of the Contents pages. I don't know if they used that in 2010, but it's worth a look.
Or, Google the designer and see if she has a website that might have a 'contact me' link.
Good for you for paying attention to this, and good luck!
