locked away in my cupboard.....out of sight but NOT out of mind
You are talking about your books and not you aren't you mugglemum!

So you are going for all three!. I do like the US cover but there is something about the design of the cover of the UK edition that sort of makes it look like it's been around for generations and adds to the idea that these stories have been told to witches and wizards for centuries.
It is a shame that you have lock all this stuff away. I'm pretty lucky in the fact that all my HP stuff is in my bedroom which doesn't get the sun streaming in all day and i also have my blind shut all the time which enables me to display all my stuff without the worry of everything fading.
Because of the the colour of my blind too, it is never dark at all and when the sun does shine my room is bathed in a fantastic golden glow!.
