Where do you get these logos?
We make them ourselves! LogoLogo.com is a division of the DIRcreative Group, which owns a successful, brick-and-mortar graphic design company. The free logos on offer here are made in-house by our own logo designers. Some are spin-offs from paid logo design projects. The majority are designed specifically to be given away for free on LogoLogo.com.
We do not use templates or clip art in our designs, ever. Each logo is designed from scratch.
