 Some debate as to the genuineness of this stamp took place in the Irish philatelic literature during the mid-1990s with a suggestion the stamp had been fabricated from a normal fully perforated stamp with a press.This hypothesis was debunked by Foley and Ian Whyte, a Dublin stamp dealer, who both claimed such a process would damage the stamp and be scientifically impossible.Archived documents were also found that confirm the stamp was ordered and issued by the Irish postal administration.
