Not everything reproduced can be licenced. If i waited for a licence to happen for some of my full cabinet decal sets, i would be waiting forever.

Its funny, I told a certain someone in Melbourne I was going to print n reproduce Black Knight 2000 cabinet decals, cause there were none on the market, then a certain someone, who doesnt hold any licence, but is friends with a former licence holder, produced a whack of really great ones. It saved me alot of time n effort, and alot of Black Knight 2000 owners all over the world are now very happy.

If the licence exists, support it. If it doesnt, get creative for your own personal machines.
