On 8 September 1868, Mexico issued a new Hidalgo design, referred to by collectors as the "Full Faced Hidalgo". The stamps were lithographed and issued both with and without perforations in denominations of 6c, 12c, 25c, 50c, and 100c. Two issues have been identified, the first with the numbers thinner and without a period; the second issue with thicker numbers followed by a period. There also are a multitude of minor variants and plate flaws, all of which, combined with the various overprints used, led Pulver to state that "In many respects, the issue of 1868–72 offers almost everything a specialist could want."
