Unknown wooden object

[Peter B.]

Last year I was on holiday in Stockholm and discovered an interesting decorative object in my hotel room:

A wooden object, about 1.5 meters long, slightly curved with pointed ends and a rectangular cutout in the middle.

The points are capped with iron, and to the right and left of the cutout are two horn spikes, attached with leather.

Does anyone have any idea what it could be?

At first, I thought it might be a carrying frame, but the sharp edges of the cutout would make it rather uncomfortable for that purpose.

There's also a sticker from the seller on the back, written in Chinese (?) script. Perhaps someone can read it?

Best regards
Peter
