Another illustration I have been working on lately is the Waltzing Weiner Dogs - based on a painting I did several years ago: http://wiener-dog.com/waltzingwienersB.html. This one is re-created in Illustrator to make it more re-producible for shirts and products: I think this pair of loving Dachshunds would make great anniversary cards.
I will post a link here as soon as I have them up on my store. I have been making a lot of sketches of dogs and cats in Lederhosen, and hope to be able to make some finished illustrations next week. I also have some new sketches of Birthday dogs I hope to get going on - they are long overdue.
