Most TT graphics are produced by Universal Products, Goddard Kansas, using Avery materials. Most good sign shops have access to U-P or Avery products. Be prepared for a crazy high price as this material is not cheep.
A lot of the newer stuff is printed, at this point there is no exact match.
Universal Products is wholesale only, they will not help you. They sell there graphic products through distributors.
I just looked at your pictures, They are printed graphics.
