Please read carefully the Google branding guidelines to better understand how to use the GEG logo (below).
Please note we highly encourage you NOT to use the Google logo but rather the GEG brand when creating materials for meet-ups or groups. This way it is clear to the rest of the world that this is a GEG event and not a Google hosted event. You can see how that may be confusing if you use the Google logo.
In addition, GEG branding is only for promoting your GEG group and events, you cannot use the GEG branding to create business cards.
Please also review the Schools Going Google Branding guidelines (below). Although these guidelines use the Google for Education logo, you can apply the same guidelines when using the GEG logo.
