Iceland 10 Aur Philatelic Stamp featuring Skógafoss Waterfall

This item is an antique or vintage philatelic stamp from Iceland, denominated at 10 Aur. The primary image on the stamp depicts the majestic Skógafoss waterfall, rendered in a detailed, somewhat monochromatic blue-green or slate-blue ink against a lighter background. The waterfall is shown cascading down a rocky cliff face, with hints of foliage or distant mountains in the upper background. The denomination '10 AUR' is clearly visible in a rectangular box in the lower-left corner, and 'ISLAND' (Iceland) is prominently displayed in a similar box to its right, spanning the lower portion of the stamp. The stamp is rectangular with perforated edges, indicative of its printing method. The color palette suggests an older printing technique, likely lithography or engraving, giving it a classic postage stamp aesthetic. The condition shows significant wear, notably a prominent circular cancellation mark partially obscuring the central waterfall image and the 'ISLAND' text. This cancellation appears to be in black ink and reads 'REYKJAVIK' and some numbers, likely a date, confirming its use. The perforations appear largely intact, though some creasing or slight damage might be present on the edges. The paper has an aged, possibly slightly discolored appearance. The visible handwritten text above the stamp in the album ('unmark') might refer to it being an 'unmarked' stamp or simply a note by a collector. Given the design and denomination, it likely dates from the early to mid-20th century. The quality of printing, despite its age and cancellation, appears to be fine, with good detail in the waterfall's depiction, which is a common and iconic Icelandic subject.
