Harriete is the Queen of tin jewelery and other amazingly clever, detailed and well crafted tin artwork. She also has a blog where you can learn practical advice on the business of art. Link is on her site.
Ross Palmer Beecher, one of my all time favorite metalsmiths, has great web presence but no website of her own. The link is to a video that captures, her work, studio and her essence. She is represented by Greg Kucera in Seattle.
The Fine Art of the Tin Can: Techniques and Inspirations by Bobby Hanson. Bobby's book is a great book for the beginner. Both books, the first one and the reprint are out of print but sometimes you can find them on Amazon.
No list would be complete without Tony Berlant. He may very well have been nailing tin to wood longer than any of us. There is no way for me to describe his work. Also see more of his work here at Design Faith (http://designfaith.blogspot.com/2010/08/tony-berlant.html), Kenneth Caldwell's insightful blog.
Lynda Kropman lives in South Africa and the tin she uses is different than what the artists in the U.S. find. Her work is sometimes happy, romantic or political. Lynda has a Facebook page and you can see her work at https://www.facebook.com/Lyndatinart/
Charlotte's work is wonderful and has a graphic look to it. Her work is very well thought out and intriguing. She owns a restaurant in Florida and has access to commercial tinned food stuffs and tin advertisements that many tin artists don't.
Leslie is multi talented, she's at home with a sewing machine and aluminum cans or found objects or tin snips. Leslie's work is bold, colorful and has a very appealing graphic sensibility. Click on the link and see for yourself.
Barbara creates three dimensional animals from recycled and discarded materials. She enjoys the challenge of transforming something with a past history into something new and exciting. I am particularly fond of her birds and dogs.
