Ok, so I did a search for ways to store my cards in album pages. It should be a lot easier to find the cards you need (especially if your players aren't going to be getting their dirty mits on the originals). Below are my suggestions. Other suggestions are welcome.
ACTION CARDS: Standard: Standard American Board Game Size. Dimensions: 2–1/4” x 3–1/2” (56 x 87 mm). FFG Supply code: Green
THE TINY CARDS: Mini: Mini American Board Game Size. Dimensions: 1–5/8” x 2–1/2” (41 x 63 mm). FFG Supply code: Yellow
????? Double up in a 3x5????
CAREER CARDS: Sheet: Reference sheet. Dimensions: 4” x 5” (102 x 127 mm).
