With Forge World slowly rolling out new very colourful decal sheets for the Space Marine Legions, they are starting to delete the very cool old ones!
The Sons of Horus, Death Guard and World Eaters/ War Hounds decals are now listed as "no longer available" on the Forge World site - bad news as these were amazing value!
As a War Hounds hobbyist, I got so much use out of the limited number on the World Eaters decal sheet that I can imagine anyone using those decal sheets for one of the main Legions could use them for ages!
They were not only great value, but also flexible for all kinds of models - from troops to vehicles big and small. They also had a very military rather than sci-fi look to them; simple and functional - as true operational military markings are!
