You are pre-ordering one copy of Immortal Men #1 to be signed by Jim Lee and 1 copy of Action Comics #1000 (Jim Lee cover - but unsigned) ONLINE ORDERS are for customers that want the comics mailed to them because they can not make the signing (too far away, too busy that day, whatever).
Please note your signed copy will be held until your Action Comics #1000 Jim Lee cover shows up so the two can be mailed out to you together. If you want to attend the signing, check with your local Graham Crackers Comics store to see if they still have any passes left.
