To fully use the logo the company will incorporate the words 'Connections Leadership'. Slogan: new ideas, new results, new impact ~ or ~ growing leadership & business
I need you to submit the logo mark at the dimensions Apple requests, and they take care of turning it into an icon! Specifically for displaying on the App Store, and on the iPad. So the iTunes logo mark will have all the design without the rounded corners applied. Apple will do the corners, cropping.
Needed are the application icon, App Store icon, Launch image, small icon for spotlight search results and Settings. See the column Size for iPad (in pixels) 72x72, 512x512, 1024x748, 50x50, 29x29
Please review this whole webpage about Apple’s requirements.
