The art teacher here is working on a project in which two students are interested in using trademarked images (the M for Monster Energy drinks and the DC for DC shoes). She stopped in the library this morning to ask how to have the students "cite" their sources for trademarked images. My gut feeling is to tell her have them create their own images, but now she's got me thinking about how to appropriately give credit for a trademarked image. I've been all over my copyright book and the internet and I haven't found what I need. Does anyone have any suggestions?
