It is commonly believed that even if astronomically large antimatter objects exist they are far away from our Galaxy. On the other hand, there are several cosmic missions dedicated to the search of cosmic antimatter in our neighbourhood. We discuss the observational bounds on cosmic antimatter and a model of its creation which allows for hidden but potentially observable cosmic antimatter in the Galaxy. Some unusual phenomenological manifestations of cosmic antimatter are discussed.
