The ties were one of her ventures. She also came out with a magazine - maybe 2 or 3 issues. Her attempts at business ventures probably cost Rush a lot of money.
I only have one of his ties, but I get compliments EVERY TIME I wear it. The funniest one was when my yellow dog liberal college advisor was told me how very nice it was. I bit my lip so as not to tell her who's it was (She is also the chair of my thesis committee, and has control over when/if I graduate, so I'm keeping my mouth shut till then).
