Description

This Highly Trained Thunderbird warning sign pairs a thunderbird graphic with a red WARNING header and a disclaimer about lightning related incidents. It’s printed directly on rust proof aluminum, so it can face real storms on a cabin, camp, or porch.

What is a Thunderbird? The Thunderbird is a powerful spirit bird in the traditions of many Indigenous nations of North America, said to create thunder with its wings and lightning with its eyes. The name was later borrowed for modern cryptid reports of enormous birds.

Will it hold up in real storms? Yes. The aluminum is rust proof and UV coated, so rain, snow, and summer sun won’t ruin it. Choose With Holes and screw it to a post or cabin wall so wind can’t take it.
