Luxembourg year 1907/20 stamps Porto full set MH

The Luxembourg “Porto” stamps issued between 1907 and 1920 are a notable series for stamp collectors. These stamps, also known as postage due stamps, were used to indicate that postage had not been fully paid and additional postage was required upon delivery.

The set from this period typically includes stamps with various denominations, each designed to serve different postal rates. Collectors often seek these stamps in mint condition, and they can be found in both hinged (MH) and never hinged (MNH) states.
