As the picture shows and the web site states, it comes with an American Flag on it so to me that would mean they’ll ship it to you or they may have a distributor in the USA. I’d contact them to find out if you’re serious.
The British price is 375 pounds. Converted to dollars that’s $600 USD, plus shipping!
They sound like they’re well-made:
“All our models are high quality, durable, cold cast poly-resin & fibre-glass, not cheaper plastic or single-skin resin copies. The detail & modeling of these sculptures is superb. Well cared for, models supplied by the Jolly Roger will give you & your customers pleasure for many years to come. We recommend that all models & point-of sale items which are going to be used outdoors be given a protective coat of clear lacquer or exterior varnish.” Should be durable.
If you get 3+ years out of it, that’s pretty cheap marketing. Since it’s 6′ tall, you’d need to be able to transport it if you’re mobile. I say Go For It! (You may be able to negotiate on the Price and Shipping)
