World's first postage stamp made of Rubber
On 28th September 2018, Spain issued the World's first postage stamp made of rubber to commemorate the 200th birth anniversary of Cosme García Sáez, a Spanish inventor. Cosme García Sáez was born in Logroño in 1818. The stamp depicts Garcia and 2 of his inventions, a submersible and a seal impression which depicts the year when it was adopted by the postal service.
A submarine is a fully self-sufficient craft, capable of independent cruising with its own power supply and air renewal system, whereas a submersible is a remotely operated vehicle usually supported by a nearby surface vessel.
He offered several improvements to the post, where he built sealing machines in post offices. It is a machine for all kinds of ink stamps to date letters and other forms. I was adopted by the Spanish Postal Service in 1857, for more than twenty years. The inventor himself was in charge of instructing on its handling.
