How can I tell what printing I have (from looking at the outside of the box)?

How can I tell what printing I have (from looking at the outside of the box)?

• Core game first printing has both the >G and Fabled Nexus logos.
• Core game second printing has only the >G logo.
• Core game third and fourth printing show the printing number underneath the bar code.
• Core game fifth and sixth printing both show "5th edition" under the bar code. (Whoops.) They can be distinguished on the exterior by the Greater Than Games logo directly over the UPC symbol - the 5th printing has a shades-of-blue die above the text "greater/than/games" while the 6th printing has a blue-and-white die nestled below a larger, all-caps "GREATER THAN GAMES" - see Telling 5th and 6th printings apart for photos of the two logos.
• Core game seventh and eighth printings show the printing number underneath the bar code.
• Branch & Claw second and third printing show the printing number underneath the bar code.
• Branch & Claw fourth printing shows "5th edition" under the bar code. (Whoops.)
• Branch & Claw then skipped to 7th printing (in order to sync up with core-game printings), which is shown underneath the bar code.
• Promo Spirits (Wildfire and Serpent) second-and-onwards printings have "Add a Presence" instead of "Add Presence" as reminder text under Growth options.
