Stego-Squid Festival Flyer

Here's part of a cross-over between my state cryptids blog and my "found object" fiction project, The Astarapomp Dossier

This is a flyer for a fictional festival in Grenhaven, Connecticut (my answer to H. P. Lovecraft's Arkham) celebrating the mysterious (and also fictional) Stego-squids that inhabit the estuary at the mouth of the Connecticut River.

Considering how big the Connecticut River is, and how important it has been to maritime history and trade in New England, it's rather sad that the river has no famous monsters to call its own. So I made some! See if you can guess what sort of creature the Stego-squid actually is. (Hint: it's not actually a cephalopod)
