I REALLY like the Turn of the Cards album cover art: it's the logo, background image, and default profile image of this site.
There was a gorgeous promotional poster for the album back in the day -- two versions in fact, with different color hues. I have both, but they are not in a condition that would pass the Wife Acceptance Factor
for wall art, no matter how high the memorabilia/collectible value.
Photoshop to the rescue: I scanned the poster in sections, combined them in PhotoShop, retouched the folds, creases, and other blemishes, printed it on 16x24 inch metallic photo paper, had Annie and Michael sign it during the June tour, and got it custom matted and framed. It came out rather well, I must say (and it definitely passes the WAF
Note that image of Annie is different from what appeared on the album back cover.
