It's a very lovely cover. Clearly not showing a scene in the Peak District or anywhere else this side of Australia - it references Marty's emblamatic design and has its feet firmly fixed with Australian roots.
If it's not in the box set, you might be tempted to get the CD just to have Mark's pic and a "best of" CD for ease of reference. A fiver on pre-order doesn't add megabucks to the grand total after you've bitten off the cost of the box set.
I haven't pre-ordered the best of myself (yet) though

The box is quite a big chew to start with.
I see it comes with a Valentine's Day present too, which is very romantic of you bdroop or whoever came up with that notion. Does Rudolph (not you, rednosed reindeer

) not play for the boxsetters?
Whilst on the subject of trees, I found myself at one of Manchester's art galleries at the weekend - The Whitworth - and they have an exhibition on at the moment of pictorial art built around the theme of trees - including a couple of Willam Blake's book illustrations. I prefer the new CD cover to everything I saw in there!
