Can anyone tell me how to go about finding out if an image is copywrited?
I'll be specific: I want to use the "Keep Calm and Carry Yarn" image (similar to the Keep Calm and Carry On posters that are everywhere) for some crafts that I would sell at a craft fair, but I don't know how to find out if it's OK to do so.
I've seen this image on mugs, shirts, bags, stitch markers, etc. made by other individuals and by manufacturers.
Does anyone have a clue?
