The Kits of origin are by Stefano Sartorello. Acrylic painting with oil washes. Base built on 2 levels precisely to ensure that all 3 subjects can be seen .. Worked on polystyrene to create the hill and then covered with artificial grass carpets and other railway model materials. The scale should be around 75mm I think even if I remember correctly. They are 2 distinct kits the male and the female with puppy.
