I was goofing around in Adobe Illustrator and produced the following. Click through to download vector PDFs. I might put these up on an on-demand T-shirt site.
The first two are, of course, based on Campagnolo logos. The second one reads “Brevetti Internazionale” (International Patents) in the original; here, it says the same thing in Japanese. The first one reads “Prodotti Speciali” (Special or Specialized Products). Spreading the Japanese text for that between the top and bottom would look a bit plain, so the top half is the equivalent in Japanese, and the bottom half is “International Patents” in Japanese. The third is based on the “STP” logo.
