You'll have to break it down
I think there is no other way, but why would one do that ?
Well I'm not saying that I would break it down. I'm asking how it was created. Is there somewhere inside a private key or something?
As far as I k ow the private key is inside however the only way to open it is to disassemble it but the screws need to be heated a lot before they can be opened.
Alternatively it can always be broken but why break a piece of art?
In response to the last few posts:
I created these with the idea that they would never be opened. If one did need to get inside they could break the glass and cut out the private key as shown in this example:

Please consider these artworks first, cold storage second. I like to think of the 'bits' as a medium in each piece, intended to stay with the piece.
Something I've learned from experience is that if you must destroy something to access your bitcoins, you tend to hold onto them.
