Lovely Daher Song Bird Enamelware Serving Tray English

This is a really beautiful enamelware serving tray designed by Daher of Long Island, N.Y. and made in England. This has 4 different birds, probably songbirds, sitting on what looks like cherry blossoms. It is shades of green, pink, cream, gold, or tan and many other shades. It measures 13.5 inches square and is in excellent condition, no dents and only one thin scratch on the edge, other than that, very little, if any other scratches to the top. I has a couple of surface scratches to the paint on the bottom, nothing major. The design looks vintage, but I have no idea of the age.
