I think Brandon Bonds black and grey is not as creative as Tony Mancia but thats just my pick, both are fantastic artists,
Mr Tyrrell is VERY hard to get hold of, he usually stops in a local shop he is friends with and tattoos a day or two before he goes to ceonvention, this is the best time to catch him, he will have nothing booked, he doesnt announce it, you have to know where he hangs out…….otherwise you can get booked at a convention, get him first day, first hour he is there
