For someone with a mindset and ability the replication of a postcard of any type with or without message, with or without period postage stamp affixed, and with or without replicated cancellation whether machine applied or hand stamped is a simple undertaking. Many of the currencies of countries of the world are counterfeited today and have been since their introduction and this offers a much greater degree of difficulty than the replication of a post card but is no obstacle for those who are determined to do so. If mankind possesses the ability, knowledge, technology, and fortitude necessary put a man on the moon and safely return him to this planet then replication of a postcard is mere childs play.
Postcards of the Third Reich are interesting, historical, artistic, and often colorful. As such they are widely collected.
