I love the cachet of the Charter Oak!
Indeed, those "classic" looking cachets on the old First Day Covers were very nice. The Charter Oak one (CT Tercentenary) previously posted is a Grandy (772-1) cachet. However, the cancellation of April 27, 1936, is really the second day of issue or the "first day on nationwide sale" ... not the first day of issue. Back then, the "First Day of Issue" was limited to the issuing city only, in this case Hartford, CT.
Here are two from my collection, illustrating the Hartford, CT postmark of
April 26, 1936:
This is a 772-2 (Ioor Purple/Black cachet ... they came in other colors, too):

This is a 772-9 (Anderson Cachet):

...and that concludes our first day cover lesson for today!
