'Go North' is partly correct. We are allowed to reuse our own work, as long as it is not sold to a client.
And yes, the shield shape is identical to the one found in another contest, but that's it. All other elements are different: Font, colour and additional shapes. AND that customer bought and paid for a fancy metallic Photoshop design in EPS that is impossible to do in vector format. Not the flat Illustrator vector file.
So the philosophical conclusion from the reasoning that a shape can't be reused, effectively rules out all squares, rectangles, circle's ovals and what have you, since they've been used before? Boy, that would render us with very little shapes in the future :-)
CH was considerate to remove these for me here. Thanks. I would have done that myself, but I had to await approval/payment from the customer first. Just because you win, doesn't necessarily mean that everything is kosher with the business side. Until then, it is the designers property.
