What a day. immersing myself in stamps....
First Stamp: Scott #107, Engraved, Unwatermarked perf 12. Hidalgo 1874-80
Benito Juarez Revenues up close. Just because, I like the cancellation/writing
1884 Hidalgo, Wove or Laid paper (not sure), perf 12 - I love these stamps.
#458 1910 Civil war issues issues Juan Aldama, overprinted (I think - practicing for when my Album get here)
#577 1916 perf 15 Barril overprint surcharge Josefa Ortiz part of the Civil war issues - again I think :)
Others I still need to catalogue - just like them.
