Know-How Exchange : Student Questions

Hello I just disovered this site and I hope there will be someone able to help me. I'm an Argentinian student and I would need to know where I could get specific information about the Mc Doandls logo. Its history, what the colors mean, what the arches mean, when it was created, and all additional info about this matter. I've been trying to find this in google or yahoo but I did not come up with any good answer. My group and I are working about the Mc corporation at University and this info is really important to us. I would appriciate someone telling me where I could get the information. Thank you
