Antique Card Table with Petit Point Embroidery Insert

This magnificent card table was left to my mother's great aunt by her old aunt, dating it back to about 1830. The embroidery is signed B. Coen and it was done in Belgium. As you can see in the picture, it is placed on a heavy wood base, and can be raised to vertical, tilted to be displayed, or flat to be used as a card table. I would love to find out more about it, and think it may be one of a kind.
