I agree things like "INC" and "LLC" are pretty corny to include in a logo or
sign layout. I can't think of any national retail business, restaurant chain, etc that includes that nonsense in their logo.
Nike, Inc. doesn't stick their legal "Inc." junk into their Swoosh icon. Any major business typically tries to strip away as much extraneous stuff as they can off of their brand.
Another thing I really don't like in most
sign layouts: phone numbers. They're usually a waste of valuable layout space. They're instantly forgettable unless someone wants to write it down on
paper after seeing it on a
sign. No one is doing that while driving a vehicle. But they don't have to either. Pretty much all of us have smart phones these days. We can literally ask our phones to call that business without typing in a number. There are exceptions, such as a real estate/construction site
sign where two or more phone numbers and agent/broker names are listed. But that's different from a primary street
sign or building
sign for a business. I think phone numbers on the main
signs for a business make that business look more
small time. National companies rarely put that kind of junk on their
signs.
