Jamaica 1932 2 1/2d Blue Mountains Definitive Stamp

This is a used 1932 definitive postage and revenue stamp from Jamaica, featuring a bicolored design with a blue frame and a slate-green center (vignette). The central image depicts the Blue Mountains of Jamaica, identifying the location as 'Blue Mountains 7388 Feet' in tiny text. The stamp is physically rectangular, mounted on a black protective background within a philatelic collection. It exhibits clear perforations on all four sides, though some show unevenness consistent with age and separation. A prominent feature is the heavy black wavy-line postal cancellation (slogan or machine cancel) running horizontally across the center-left, indicating it was postally used. The denomination '2 1/2d' is centered at the bottom, flanked by 'POSTAGE' and 'REVENUE' in the lower corners. The overall condition shows some minor toning and slight corner wear, but the design remains legible with good registration between the two colors. The stamp is mounted on gridded paper accompanied by Dutch typewriter text describing the geography of Jamaica, and it is cataloged with the Yvert reference '114'.
