This is a tuck box for the Space Dealer Cards. It prints onto A4 (I use 220gsm photo paper) and then needs cutting out, scoring and gluing. There is a pictorial guide in the "Creative" images section. The image is the box front image uploaded to BGG by Tobias Stapelfeldt (the game designer) and the card list on the back is an edit of Sterling Babcock's SD_Card_Catalog_V4.xls spreadsheet. v2_2 has some cosmetic improvements over v2_1 especially at the joins between sides. However, frankly I can't tell v2_1 and v2_2 apart side by side after construction.
