There are quite a number of various sports teams, native to the United States, which use various kinds of logos to represent themselves with. The team with an eagle in the logo is the Philadelphia Eagles football team.
Barclays uses a blue eagle as their logo.
Kmart uses a K as its logo.
The US basketball DREAM logo uses a custom font called TS2. It was custom made for this logo and therefore may not be able to be used for personal typing and other logos.
The logo that the NFL uses was created in 1960.

I'm pretty sure it is Aeropostale that uses the butterfly logo...but I'm not so sure any designer uses it. :-)

Well, Perl Coding's logo is a Camel.
