This attractive 1977 Christmas Island issue forms part of the popular Twelve Days of Christmas thematic series, illustrating scenes such as “Two Turtle Doves,” “Four Calling Birds,” “Seven Swans a-Swimming,” and “Ten Lords a-Leaping.” Designed in a colorful illustrative style typical of late-1970s Commonwealth commemoratives, the stamps appeal strongly to Christmas, bird, and thematic collectors. The combination of festive storytelling imagery and wildlife subjects makes the set especially desirable for topical collections. Well-centered mint examples with fresh gum are commonly sought by collectors assembling complete thematic Christmas Island Christmas series.
