Aquatic & Marine Decor
Novelty aquatic and marine signs, art prints, greeting cards, and mousepads for ocean lovers, pond keepers, and reef tank enthusiasts, made in the USA in our Henniker NH studio.
For the people who know that the most interesting personalities often live in water, and whose home decor should reflect that with the appropriate level of commitment. This is the full aquatic and marine collection in one place, spanning novelty metal warning signs, caution crossing signs, art prints, linen greeting cards, and mousepads, all featuring original aquatic creature artwork exclusive to Designs by Linda Nee.
An octopus relaxing in a clawfoot bathtub rendered as a proper wall art print. A steampunk octopus greeting card for the cephalopod enthusiast who also appreciates industrial design. A bookish octopus card for the one who reads while floating. A penguin in a Santa hat wall art print for the coastal holiday decorator.
A cute penguin Christmas mousepad. A highly trained gharial with documented property protection responsibilities. A hippopotamus with a formal XING caution sign, because some crossings simply require official signage.
All aquatic and marine decor is designed in our Henniker, New Hampshire studio and made in the USA. Every piece carries original artwork exclusive to Designs by Linda Nee. Metal signs are printed directly onto heavy gauge rust-proof aluminum using UV resistant ink, with no decals and no vinyl, and arrive with pre-drilled mounting holes ready to hang indoors or outdoors. Art prints are available on archival fine art paper or aluminum metal, printed to order in multiple sizes. Greeting cards are printed on premium Red River linen cardstock with archival-safe inks. Mousepads are precision-finished with the same studio illustration.
Aquatic and marine creatures across this collection include octopus, cichlid, plecostomus, otters, archerfish, frogs, gharial, anemone, fish, alligators, hippopotamus, penguins, and more across freshwater, pond, reef tank, and ocean species. Styles span novelty humor warning signs, bright caution yellow crossing and XING signs, whimsical fine art prints, and bookish creature greeting cards.
Strong starting points include the Octopus in Bathtub Wall Art Print, the Funny Otters Warning Sign, the Steampunk Octopus Greeting Card, the Otter Crossing Caution Sign, and the Hippopotamus XING Caution Sign.
