Record Store Day HB Picture Disk

[The Holy Bum-Bum]

So, we've seen mention of a Holy Bible picture disc that's going to be released as an exclusive on Record Store Day. There's nothing to say if it's going to be UK or US (or both),

How does this work, in general? I'm not a big vinyl collector, so know nothing about the Record Store Day thing, other than it makes things very difficult to buy! Any info on it would be appreciated - cheers!
