Antique Large Thai Siam Silver Serving Spoon Incised Buddha, Coiled Serpent Tail

I'm offering for sale an Antique Large Thai Siam Silver Serving Spoon Incised Buddha, Coiled Serpent Tail (I believe the tail may be a representation of a cobra tail). I've owned this silver spoon for a very long time & now I'm selling it. I'm almost positive this is not sterling but rather either silverplate or a different metal, but the design incised upon it is quite striking! There's a buddha w/his eyes closed in prayer, & what I think are dragon flowers flowing down the handle. The design is both punched & incised. Near where the handle meets the edge of the bowl, the spoon features a delicate design. The bowl of the spoon is huge at approximately 3 1/2" long x approx. 2 1/4" wide. The curved handle is approximately 5 1/4" long w/the protruding coiled serpent tail being approx. 7/8" high. The total length is approx. 9". I'm not sure of the age, but it could be a be a mid century item. View all photos prior to purchase as I do not accept returns. AMH
