Sometime in the past 6 months, a new website was making the rounds, and now I can't seem to find it. It was basically an online version of Kuwayama's Trademarks & Symbols—a searchable/filterable gallery of logos. It kind of reminded me of the Noun Project, but for corporate identity. Anyone have the link?
