That text is perfect; love the paper grain; great work!
Concerning colors Trog and Rex seem to be part of the bezel (printed on plastic?) and their color is not the same as the paper. Looking at available pictures the color seems matte white/very light grey (even may have some bluish nuance). Paper color: personally I'd make it slightly less yellowish as most of that yellow component is clearly due to age. Unless of course we want to show a realistic aged strip.
