| 背面描述 | The reverse carries a panoramic landscape vignette of a snow-dusted border village with coniferous trees, over which a military helicopter is rendered in detailed intaglio. A fixed-wing jet aircraft appears at upper centre against cloud formations. To the right, the outline map of Poland frames an intaglio Polish Eagle in white on a blue ground. A fine microprint band runs along the upper margin, and guilloche rosettes provide background security patterning. |
