Please make sure that you use PRINT logos for print applications, and WEB logos for the web.
There are different types of logos for different applications. A web logo used for print will look bad. A print logo used for the web will either take forever to show up, or will not show up at all.
The print collection also includes black & white versions of these logos.
If what you need is not here, please contact email@example.com
All logos in a zip file.
Some have transparent backgrounds. There are a number of file formats.
Please check resolution. All of these are a minimum of 300 dpi. One file is vector, for use in banners, large posters, and other serious enlargements.
