Almost everyone knows it, the logo makes it clear to the few clueless. ;-D
Spreadshirt makes you look good and it makes you unique.
Why wear the stuff everybody has, you can have your own label in just a few minutes…
The logo is easy to keep in mind and the typo is clear and modern. You don´t need much more.
Check the additional information for some more images and thoughts…
As promised some more information and images… 
Typo: The famous “Frutiger” really kicks your a**.
It´s a wonderful and modern sans-serif font you can look at for hours. It´s flow is nice and never boring.
I think it fits very well for Spreadshirt.
Graphics: Oh, these little guys are so cute (and easy to remember).
Everybody loves little figures and here you got them very pure.
Three of them are not unhappy but one is really thrilled (and he spreads his feelings with his arms).
Wonder why?
They all got cool shirts but that one … yeah, he got his one from Spreadshirt, right.
Combination: We got little figures showing that you can be really happy with your clothes.
And there is this cool slogan “Spreadshirt - Your own label”.
You get the message!
Spreadshirt can help you to be happy by giving you the chance to make your clothes look like you want to.
Wow. (You like it, dont´you? ;-D)
Some more samples…
Ok, here are some more samples (with TLD, on a shirt, outlined)
Whoah, thousands or millions of combinations are easily possible just by changing the color, that´s great.
I really like that in this kind of logo. 
I am really happy to be given the chance to take part in this contest and I would like to say thanks to Spreadshirt for this contest and good luck to all other designers and contestants. Thanks.
