I just got a vintage G1 Hun-gurrr in great condition and want to display him. The spot I have picked doesn't get any direct sunlight but is by a window and the room can get bright. Since I have mostly G1 reissues I don't know if white vintage TFs have yellowing issues and I'd hate to mess this guy up. Does Hun-gurrr have any yellowing issues I should be concerned about?? Thanks in advance.
