I assume you’re trying to wall mount? You could forge up a mounting point or use existing hardware but it comes down to glue either way. Someone posted a keyhole-style mount ages ago. Let me go find it.
Of course you could also glue a standard sawtooth style picture hanger on there too.
If you’re really feeling industrious you could engrave a very small pocket or lightly score the outline for the sawtooth/keyhole, it would help align things. Maybe not worth it, ymmv.
