FREE cache of vector logos from Brand of the World
Brands of the World is my go-to resource for vector logos. I often find myself trying to scrounge together logos for various projects I’m working on and usually begin and end here. Their collection is extensive and includes both newer and older versions as well as many variants used in other markets. Registration is free.
In fact, I used BOTW to put together this Brand Alphabet. Test your elite logo sniffing skills.
