It is 4.75 inches ( 12 cm.) high.
Made by Louis Osman ( 1924-1996) and his wife Dilys ( enamellist ), London, 1978.
Here's the description from my reference:
" The bowl echoes an African stringed drum. The cover is engraved as the sea with foaming enamelled waves.
The two sporting dolphins and the recumbent Thomson's gazelle carrying the drum are solid gold.
The base bears the words 'but always as friends'.
(Victoria and Albert Museum, London )."

Any ideas about the meaning ( symbols ) of this piece are welcome.
