DIFFERENT FONTS ON PSA LABELS?

Scrolling through Ebay last night, I noticed a few cards with different style fonts on the PSA labels. They were mostly on the older cards (pre-1990). Did the company switch fonts at some point? I checked the cert numbers and they popped up. Just wondering. I tried searching the forums, but came up empty.
Thanks,
Kevin

I would love an expert or PSA representative to give us the detailed answer.
