A double-sided quarter-legal-page player aid, that is intended for lamination.

On one side, the rules are summarized, while the other side serves as a reminder for each card type (colour).
Once laminated, the card can be used as individual score sheets, as there is space to note the score of each category.

This is my preferred system for game explanation, because 7 Wonders is super-simple but it can seem complicated at first. I like to have an outline of the scoring, for reference during the game.

Two copies of the file are included, pdf for quick printing and doc if you'd like to edit the file in any way.
