This is a set of mint never hinged postage stamps from Ajman, commemorating Johannes Kepler's 400th anniversary as an astronomer. The colorful stamps feature images related to space and the United Arab Emirates, including the country's denomination currency, the riyal. The VF (Very Fine) grade stamps were issued in 1971 and originate from the Emirate region. They come uncertified and are a great addition to any stamp collection.
