This complete sheet of 100 stamps from Macau was issued in 1958 as part of a postal tax series dedicated to charitable causes, particularly under the invocation of Our Lady of Mercies. The stamp, printed in olive green, features a neoclassical depiction of a robed female figure with outstretched arms, surrounded by angels and floral elements, symbolizing protection and benevolence. The text "ASSISTENCIA" underscores the stamp’s purpose to support social aid through postal taxation. The denomination is 1 avo, with inscriptions in both Portuguese and Chinese. Designed by José Neves Castel, the stamps were produced via lithographic printing and perforated at gauge 11¾. This full sheet is mint never hinged (MNH), exhibiting clean gum and sharp perforations, though it shows minor creases and small marginal tears consistent with sheet storage. This issue is catalogued under Michel MO Z15, Scott MO RA14, Yvert et Tellier MO 386, Stanley Gibbons MO C468, and Barefoot MO A22. Its preservation in full sheet format adds significant value for thematic and regional collectors. Estimate "$100 – 140"
