If "Cal" is a registered name associated with the university I'd avoid it. It seems kind of generic though. Like here at Virginia Tech, you can print "Tech" by itself without copyright issues.
Yep, I'm going with simply "Yale 1954". I see no obvious reference to any college. I found a city of Yale, a school district called Yale, a forklift company, and of course, a lock company.Interesting thing, this got kicked my way from Custom Ink!Apparently a custy submitted some forbidden artwork (logo). After talking to me, the CI guy contacted her and gave her my name and told her that I could probably advise her as to how to proceed without stepping on any toes, and still produce something she'd like. Where and how he came up with me is a mystery. (He either didn't mention Custom Ink or I missed that part, or I would have asked)
