ANTIGUA 1969 REDONDA PHOSPHATE INDUSTRY FIRST AND FINAL IMPERF PROOFS
Redonda Phosphate Industry Anniversary first and final imperforate proofs in lavish Enschedé presentation folder. First proofs of 15c and 50c lack emphasis of mining areas on island while 25c lacks the inscription and features a yellow sky (rather than white). Magnificent. The only such folder we have seen. Minor scuffing on reverse otherwise fine. Stamps mint never hinged. SG249var-251var; SC221var-223var
