Description

This flatwoods monster caution research sign brings vintage caution-sign humor to cabins, garages, and property lines, warning visitors about a legendary cryptid instead of a real hazard. Fun fact: pop culture treatments of the Flatwoods Monster often give it a spade-shaped or heart-shaped head, a detail traced back to the original witness sketches.

It's a favorite gift for cryptid hunters, folklore fans, and anyone who loves a good legend. Every sign is made to order and custom-imprinted in the USA, right in our Henniker, New Hampshire studio.

Does this sign come with mounting holes? Yes – every size ships with or without pre-drilled mounting holes on the shorter ends, your choice at checkout.

Is this sign safe to hang outdoors? Yes, it's rustproof, UV-protected aluminum built to handle sun, rain, and snow for years without fading.
