There are a lot of limited edition prints that you can buy, prices range from $300-400. There are also various sculptures and brozes (not all Wyland) that start from $200. I've bought a couple of Tim Cotterill's (Tim the Frogman) works from the Wyland Galleries (
http://www.frogmanbronze.com/ ) .
When I was in Hawaii I visited a couple of the galleries there and Wyland was doing a few special shows to celebrate his 20 ( I think it was 20) years in business. As part of the show (which was him and 4 or 5 of the other artists that show at his gallery) Wyland painted a work in oil that was auctioned at the end of the show. At the first show I didn't bid, mostly because I was a little concerned about the logistics of getting the painting home, but I was very suprised how, comparitively, cheaply it sold for so I returned a few days later , did bid and ended up with a genuine Wyland original oil for a lot less than they usually retail at. So I guess I count as someone that has bought an original from one of the galleries, even if not from those at WDW. I would say that my impression is that the galleries that are in high profile areas like WDW and Universal Studios are "written off" as advertising outlets to some degree. I don't doubt that they do sell some works and that the sales prices are relatively high ( as are most original pieces of art from well known artisits) but I think that where the galleries are of value to the artist is that they sow the seed in peoples minds that they might at some time like to buy one of his works. I know that is the case for myself.
I would guess that in most of his galleries they have a higher ratio of "serious buyers" , I have seen items being bought in WDW but I would guess that more business is done over the phone,fax or internet once people return home and have a little more time to think things over. As many of the original works run to $10,000+ it's not often they will sell to an impulse buyer, but as most items would need to be shipped to a home address anyway I don't think they need to have that many customers walking out the shop with a $20,000 painting wrapped in brown parper under their arms

.
IMHO Wyland is an excellent artist, I like the subject matter plus I admire his efforts and ambitions to raise awareness of conservation matters around the world. You don't need to spend thousands of dollars to own a piece of his work, limited edition prints are available from a few hundred dollars.
Just found out DG Jana
