The sculpting on Hat's Gallic Warband slingers really isn't that great. The legs don't have a very natural appearance, and the faces have barely any detail. Still, I'm pleased with the overall look.
You can only see two of the shields in this photo, but for the painted designs I used the book, Celtic Designs from the British Museum, by Ian Stead. The designs in this book are from pottery, weapons, etc. I picked out small parts within the larger designs to paint as La Tene style shield blazons. Also see, Early Celtic Designs, by the same author. This was the British edition of the same book. Ian Stead is a archaeologist specializing in Iron Age Britain.
