Pottery Wall Plaque Marked BAS Deruta Italy

This Pottery Wall Plaque marked BAS Deruta Italy belongs to a client of mine.

by Jan, Cargo Direct (South Africa)

I am a ceramic conservator, and although the wall plaque is in perfect condition albeit a llitle dusty. I cannot find any reference to it.

It is a three cornered wall plate with folded edges, tied with gilded laces.

The edges have a raised design and the centre is painted in a aquamarine colour on a cream base.

The illustration is in cream, outlined in black (a with a vase or ewer with flower stems and a candle holder and candle with a lit flame and a potted plant).

The marks on the back are BAS Deruta Italy and a diamond with a dot in the centre.

There is a rumour it came from a museum in North Africa (I am in South Africa - the owner says it is from a place called Dekka). Although I cannot verify this.

I can find reference to Deruta Pottery in Italy (maiolica) but none of the images I have seen show anything quite like this.

If anyone can help identify it I would be most grateful.
Thanks, Jan
