Last time I was shopping at Miss Selfridge they had an "vintage idol print t-shirt" with an image of Jarvis on. Someone might be interested in that but considering it didn't even mention his name in the description be prepared to see numourous trendy young things who don't even know who he is wearing it too.
(I might still bear some resentment from the time Top Shop sold a shirt with him on and I tried to talk to a girl in my college class wearing one about him only for her to ask me who he is...)
