Use UPS. The costs should be around 60,- GBP and insurance is 1.1%

Thanks both

sixty quid for a large painting with UPS. are you sure?

    I would imagine a large painting would need some very secure packing if it is on stretched canvas.

I've used UPS and found them very expensive. Thought 60 quid was a very low price.

Within UK/Europe 60pounds will barely do for 1m x 1m but which country are you referring from/to?
My experience is the local office works fine when using UK or US -> Holland.
Fact being that all the risk is during transit.
The service you chose wont make the difference imo, just try to get it as shockproof as possible.

I only sended and received prints in sturdy tubes from US/UK to Holland so far using either USPS UPS or RoyalMail & upgrade to their priority services. Most use air traffic transfer but it being a fairely large outer box their rates could scare you. UPS has always been nice to me btw.

35kg? Yikes! That's going to cost a lot!

Isn't media mail less expensive via USPS?

Having been to the Warhol exhibition in NY and pondering how the huge Chairman Mao canvas got to the Whitney - I found this article interesting.

We often talk about Flight Logistics here - but this is another level.

Shipping museum-grade art is a specialist business: only a handful of top-flight firms, among them the London-based Momart and Constantine, are trusted by major institutions. Even so, most museums also insist that art on loan travels at all times with a courier, ideally a conservator. This is known as “nail to nail”: one person stays with one work from the moment it is taken down in Room 38A of the V&A to the moment it goes on to the wall in a museum in Shanghai 5,700 miles away. Unless physically impossible, they need to stick with the artefact – or at least the crate it is travelling in – every step of the way.

great post and interesting read.

Companies like Flight Logistics have been recommended to me.
But theres too many variables, size of art, value, where its going to and from, are you dropping it off at the courier or are they collecting etc to give you any idea of if you're getting ripped off or not

Flight Logistics most definitely

Just to give you an idea then, someone i sold a print to in America (i'm UK) 50x70cm frame / package weight 2.8kg, was charged $310 by flight logistics

I'd take it on the flight as 'carry on' luggage. I've done it before on a transatlantic flight. Had the tube with me next to my leg as I didn't want anyone to manipulate it while looking for stuff in the overhead compartment. It wasn't a super wide tube though. I don't know how long your flight is but I think it's a good option. It's a domestic flight, no customs, stick that wide tube between your legs and bring it to your new home!
