If you are looking for a holiday gift for a coffee drinker, or simply a funny gag gift, this ceramic coffee mug is very meta. Available on Etsy from Mister Mugs, the cup has a simple illustration of another coffee cup on it. The drawing could be a reusable tumbler or a to-go cup, depending on your disposition. The vessel has a sturdy, vintage diner design with a slight curve.
Of course, the ceramic coffee mug could be a present for any occasion and need not be exclusive to Christmas. You also don't need to stick to coffee; this mug will be suitable for any hot liquid such as tea, hot chocolate or apple cider.
