Here's something to research about that Connecticut Statehood Cover (Scott #772). I believe it's a William Weiss Cachet. The following quotation talks about it thusly:
Quote:
William Weiss was a Cachetmaker who operated under the trade name National Cachet Publishing Service.
According to Monty et al., 2006, p. 47, the First National Cachet Publishing Service was the #733-GP5 for the 3c Byrd (10/13/33). According to Monty, p. 59, the First William Weiss Cachet under his own name was a 2d Day DC Cachet the #772-19 3c Connecticut, pm Wash DC 4/27/35.

I don't have the noted reference books to verify it, but if the above quote is accurate, it would appear that the first William Weiss cachet "under his own name" was the Scott 772 cover shown, but with a 2nd Day of Issue Washington, DC postmark. Obviously, yours is a first day of issue Hartford, CT postmark.
I'm not sure if there's anything special about the example you scanned or not, but it may be worth checking out. I also know they did a similar cachet in orange (in addition to red).
