It's for printing cloth using a roller type technique.

 

WOW! That's nice!
Put it to work!

 

Thanks. Seems like it could be a wallpaper roller. I see a lot of these were turned into lamps.

 

I would suggest that it's more for a stucco like wall treatment , on the borders.
You can see how the texturing goes all the way down to the base of the roller.
That would not show up if it were used on a hard flat surface , as only the high edge would made an impression, so the roller must have sunk deeper into the material to have the entire carved surface leave an impression.
