On goodlogo.com we do not try to have a complete collection of logos per brand, productcategory or branch. As our name says, we try to build a collection of good logos on our site. The Woolmark logo definitely qualifies as such a good logo! For this reason it was added on our site, already a long time ago. At that time I was adding logos at the priority of the criterium 'good' design. Not specifically on a 'per productcategory' basis. I will check the other logos you mention and will add them soon.
Hey all, I love this site. Wish all the logos had explanations. Its so insightful. I'm new to the whole logo design thing. I'm going at it myself. I admire what graphic designers do (logo design, specifically). Simplify a whole company and its motives to one recognizable shape or form. I need more logo history to help me grow... Just dropping a line.
Heartily thanks to launch An informative website "goodlogo.com" and expressly LOGO-QUIZ segment. A good- novelty by Frank Eijking and his Good-team for Worldwide brands and also for Ovan Sports Co. I am sure, our new V-checkmark logo shall beauty the LogoQuiz portion.
