The best knickknacks, gewgaws, memorabilia, you name it: it's *material culture* from the media it belongs to. Random household object adorned with images from media <<< object from that media Ditto real life too! A thing from country X that is relevant to country X is way better than a household object printed with images related to country X. - Maybe one edge case that honestly actually supports this rule: a household object that reflects the material culture - like a mug with a joke that locals would actually find funny. That's material culture!
