I've been assembling this thing for about 3 or 4 years now. I've now got Han on each basic cardback and a couple of variations to boot. I'll now slowly work on getting variations together. Not shown in the pictures because I haven't received them yet, are an ROTJ Endor Han w/camo collar and my final piece a POTF Carbonite Han.
And the entire run on one wall plus the Solo collection, both vintage and some modern stuff thrown in that I liked. The Han Solo sign came from Disney World last year. My wife bought it for that purpose when I was off in another corner of the Star Tours shop.
