Modern Plaque, Pottery Signed Bellis? 1950's-60's NR

Great design, t must be some symbolism to the three girls with the three doves....... Looks very Italian, but could also be French? I do not know the signature. Clearly hand built, look at the clay on the back. Incised 30 x 30 on the back (cm?). It is just over 30cm square or about 1' square. Frame is 17 1/2" by 17 1/2". Signature look like it could be Bellis? I am just guessing it is hard to read. Excellent condition! No chips cracks, dings or dents. 100% guarantee, this is a nice piece. I will take it back and provide a full refund if you are not 100% happy! Buyer must cover return shipping and insurance cost. Shipping flat rate $25.00 within the US, lower 48. Will be well packed. Insurance is included. Must charge NYS sales tax for NYS buyers. Thank you and good luck! Please take a look at our other auctions, listing some fun stuff!
