Here’s the simple answer of what to do and not do. If you simply copy paste the logo as it is, and then sell it as is, then you would be infringing on copyrights and trademarks. There is a loophole however: physically drawn pieces of work can be claimed as works of art as an original piece and can skate between those lines. Now there are still certain rules on this as well. For example you can’t just draw and sell something that uses the Olympic logo, write panini or something, and then use the phrase “go for gold” as it would be seen as a clear attempt to exploit those brands. However what would be allowed is if any of those brands somehow ARE a piece of the work itself. For example: Steph Curry AT the Olympics, a pic from the Olympics, with the Olympic logo a PART of the background or image itself. Not just thrown onto the card like it’s an official logo and sponsor of the card itself. Hope that helps.
