1980's Rare poss Haydee Scull Oversize Frog pottery pieces signed

These pieces although look similar, are not a set, but both signed by Haydee. From 1983 and 1984. The signature I believe is Haydee Scull's, it's a match to it. These pieces were made for my friend, an older lady of similar heritage to Haydee. First is an oversize ceramic lidded Frog box. The lid part has another small frog on it, and is decorated with a floral design. the lid does have a chip that was replaced, see pics. Size is 11" x 5 1/2". The plate is very big, 15" across and also a floral design. In very good condition. The artist did mostly 3d type mixed media pictures and are very collectible. Some go for over 1000 each and up. Unique, one of piece here, you will not find anywhere else.
