Meet the pterosaur metal warning sign that puts a prehistoric flyer on guard, with the property protected by a highly trained pterosaur and no one responsible for injury or possible death. It’s printed directly on rust proof aluminum, so it won’t peel like a decal, in six sizes for a dinosaur room, study or patio.

Is it a good gift for an adult dinosaur fan? Yes. It reads as a joke rather than a toy, so it fits a study, game room or science classroom. The 12x18 inch size is the easy pick above a bookshelf.

What are your metal signs made from?

Our metal signs are printed directly onto heavy-duty aluminum (no decals or stickers involved), giving them a durable, rust-proof finish. Each sign is proudly made in the USA at our studio in Henniker, New Hampshire.

Are your metal signs suitable for outdoor use?

Yes! Our metal signs are designed to withstand outdoor elements and feature a UV protective coating, making them ideal for both indoor and outdoor display for years to come.

How do I hang my metal sign?

Most of our signs are available with pre-drilled mounting holes for easy hanging. If you'd prefer no holes, we offer that option as well – just select it when ordering.

How do I clean my metal sign?

Metal signs can be cleaned easily with a standard glass cleaner and a soft cloth to keep the print looking bright and clear.

Can I customize a metal sign with a specific vehicle, breed, or detail that isn't listed?

In many cases, yes! If your specific vehicle, pet breed, or detail isn't listed, choose the closest matching sign. If the product page has a customization field above the "Add to Cart" button, enter your details there and we'll personalize it for you. If there's no customization field on that listing, email us with your details and we'll let you know if we can accommodate your request.

What size metal sign should I choose?

For most walls, a 9x12 in or 12x18 in sign works well as a focal point, while 16x24 in and larger suit bigger walls or garage doors. Smaller 6x6 in or 8x8 in sizes are popular for mailboxes, gates, or gift-sized pieces — check the size chart on each listing for exact placement guidance.

How long do metal signs last outdoors?

With their UV-protective coating and rustproof aluminum construction, our signs are built to stay vibrant outdoors for years through sun, rain, and snow without fading, cracking, or rusting.
