I have a question about drawing a picture tagged with Creative Common rights. I wish to create a drawing as art from a photo with Creative Common rights asking for attribution with the intent to make prints and sell. How can a drawing be attributed? Stating the source on the drawing would not be acceptable. Also, I wish to draw a train with the company name on the side with the intent to make prints and sell. Can I create a drawing as art that includes a company name with the intent to make prints and sell without permission from the company? Thank you.
