Antwerp Postmark on Liege 1939 Luik Belgian Stamp

This item is a postage stamp, likely from Belgium, featuring a blueish-grey monochromatic design. The stamp is rectangular with perforations visible around its edges, indicating it is intended for postal use. In the upper left corner, the denomination '1 FR 1.75' is printed in black, suggesting a value of 1.75 Francs. The upper right corner has text 'LIEGE 1939 LUIK', indicating the stamp commemorates or depicts something related to Liege in 1939. Below this, a landscape or cityscape appears, rendered in the same monochromatic style, with what looks like buildings or structures along a body of water or a valley. The lower section of the stamp includes the words 'BELGIQUE BELGIE', confirming its country of origin as Belgium. A prominent circular postmark partially obscures the central and lower portions of the stamp. The postmark is dark blue or black and features text that appears to read 'ANTWERPEN' (Antwerp) along the top curve, and '22.3' in the center, likely indicating a date (March 22nd). The postmark is clearly applied over the stamp's design, signifying that the stamp has been used. The stamp's condition appears fair, with the postmark being a significant and intended feature. There are no obvious tears or major creases visible, but the image resolution makes it difficult to assess minor imperfections like thinning or foxing. The paper appears slightly off-white, consistent with aged stamp paper. The style suggests a mid-20th-century design, aligning with the '1939' date.
