Polish Post Label with Price and Barcode

This item appears to be a section of a postal label or stamp from Poland. The primary physical characteristic is its rectangular shape with a serrated or perforated edge on at least the top and bottom, consistent with a tear from a roll or sheet. The background color is a light, muted off-white or beige, showing some discoloration or aging. Prominently displayed is the number "6" followed by the currency abbreviation "zł" (Złoty), indicating a value of 6 Polish Złoty. The text "6 zł" is oriented perpendicular to the main axis of the label, suggesting it was printed in a manner that would be read vertically. Below this text is a series of vertical black lines, forming a barcode or a similar machine-readable pattern. These lines vary in height; there are two taller lines flanking a row of shorter, more uniform lines. The resolution of the image makes it difficult to discern exact line thickness or spacing patterns. The overall condition suggests moderate wear, with some smudging or light soiling visible on the light background. The edges show slight fraying or wear from being separated. There are no obvious maker's marks or specific manufacturing details beyond the implied postal origin. Based on the currency and typical use of such labels, it likely dates from the late 20th century to the early 21st century. The simple design and clear monetary value indicate its primary function was for postage or a related service. The quality is functional, consistent with mass-produced printed material.
