Aye aye! Blimey!  T' addressed mail inside t' payload bay used 1936 "First Canadian Rocket Mail Flight" stamps postage that were never used because no rocket be built, 75 years later they were finally delivered t' way they were supposed to.  T' launch video is incredible and is on You Tube featurin' an onboard 'gopro' camera.
