Oh, I saw the corgi pudding poster and must have it! One of my favorites is Evie Anderson on eBay. Do visit her site with the wonderful photographs and stories about her own corgis Chloe and Gwenny-piglet. I have successfully won several of her originals and they are absolutely priceless! You can also find her shop at CafePress and I think she has also just opened a shop on Zazzle.
I am happy to own the original Evie Anderson "Hug a Fluffy"!!!
Valerie Brock also does good work with Corgi!
