Vintage Eames Era SIGNED Copper Enamel BOWL Dish

This dish/bowl is signed in script and it is unclear except fpr the Lau, maybe someone knows who it is....... It's approx. 5" in diameter across the top, the flat part of the bottom is approx. 2&1/4" in diameter and the height is approx. 1&1/4".... It's a deep royal blue with white four leaf decorations.... I don't see anything wrong with it, enameling good, no chips dings or crazing..... The bottom is rubbed, normal wear from use......
