1980 Republik Indonesia Parrot Series Philatelic Souvenir Sheet

This is a philatelic souvenir sheet from Republik Indonesia, dated 1980, featuring a series of indigenous parrots (Nuri). The sheet is printed on a vibrant yellow ground and contains multiple perforated stamps of varying denominations: 350,- (Nuri Elang), 250,- (Nuri Dada Merah), 400,- (Nuri Punggung Kuning), and several smaller denominations along the bottom edge including a 75,- and 100,- value. The artwork depicts detailed, scientifically illustrated birds perched on branches against stylized green foliage. At the top of the sheet, there are two large, symmetrical line-art illustrations of mythical or stylized birds in black ink. A distinct red pentagonal logo, likely representing the Indonesian postal service or a specific philatelic event, is visible on the left margin. The sheet maintains its original perforations, though there is a noticeable misalignment and partial overlap of the bottom row of stamps, suggesting they may have been moved or were part of a larger sheet assembly. The paper appears to be in good condition with no significant foxing or tearing evident, though the edges show slight unevenness typical of collected philatelic items. The printing quality is characteristic of late 20th-century offset lithography with clear, legible typography and rich color saturation in the bird illustrations.

I have conducted a visual examination of the 1980 Republik Indonesia Parrot Series Souvenir Sheet. This issue, celebrating indigenous Indonesian fauna, displays the high-quality offset lithography and saturation typical of the Perum Peruri printing house of that era. Based on the digital image, the sheet appears to be in 'Mint Never Hinged' (MNH) condition, with the vibrant yellow background showing no signs of UV fading or significant foxing. The artwork features the Psittrichas fulgidus (Nuri Elang) and other species with excellent registration. However, I note a significant misalignment in the bottom row of stamps; while this initially looks like an error, in this specific 1980 series, it often suggests the sheet was separated from a larger 'gutter' arrangement or suffers from minor edge trimming. The market for late 20th-century Indonesian philately is currently stable but characterized by high supply. This sheet is not considered a rarity; it was produced in significant quantities to satisfy both domestic and international topical 'Birds on Stamps' collectors. Value is primarily driven by the thematic appeal rather than scarcity. Factors limiting the value include the commonality of the 1980 bird issues and the lack of a 'specimen' overprint or specific postal history usage. Authenticity cannot be 100% verified via image alone. A physical inspection is required to check for gum integrity (to ensure it hasn't been regummed), verify the authenticity of the phosphor bands (if applicable), and inspect for hidden 'thins' or pinholes. To finalize this appraisal, I would require a high-resolution scan of the reverse side and provenance regarding its storage history.
