Generally speaking, we are unable to carry products containing a copyright or trademark protected title, name, or image. Examples of infringing material include: --pictures and/or names of celebrities --names of characters from books, films, or television shows --titles of books, feature films, television shows, or magazines --images from films, television shows, video games, or the internetAnd this doesn't apply only to the design itself, but also to the title, description and tags of the product. That's about it. I hope this might save you some time and troubles. PS Here's a tip - if you use Zazzle's "Quick create" tool to create a batch of products, they are going to be examined carefully and there is a greater chance that they will get rejected. If you create a single product, it gets published directly and while it may get rejected subsequently, this doesn't happen as often. I am not talking only about designs that are in the "grey area" of copyright, I don't condone cheating the system. But designs might get rejected due to other reasons as well, for example tag spam. I had a single product accepted, and then a batch of products with the same design and tags rejected, because of tag spam. (Even though the tags I used were all related to the design.)
PPS If you like the "Get Lucky" design, you can download the hi-res, 300ppi png file (with transparent background and without the StrayCat Graphics logo) here for free and print it at a local shop or whatever you like.
