1Equatorial Guinea BL277 was produced in 2 printings, if not more: The first printing is blue and the second is blue-violet (as seen in the non-overprinted sheets). A third printing that is magenta has been found overprinted only, and possibly a fourth printing with more green has been found on FDCs only). None of the overprints appear to be found on more than one printing.
