Danube Steam Navigation Co, cancellation in Vienna: Austria Arms 1864 5 kr. rose perf. 9½, a fine and fresh used example on June 1866 entire letter from Alt-Orsova to Vienna, tied by handwritten "AOrsova" and upon arrival by Vienna '1' three-ring numeral in black. The cover had obviously a weight of more than one loth and was taxed with '10' (kreuzer) due resulting from 5 kr. missing postage plus 5 kr. zutaxe. Horizontal file fold well away from adhesive and cancellation, some toning, an appealing combination of handwritten cancellation at the place of origin and mute security cancellation in Vienna. Signed Edwin Müller.
