Sterling Art Pieces With Fancy H Hallmark

[999Fine]

These are decorative art pieces? Flat sided. Fancy H in circle and Z in circle hallmark. Any help on what they are and who made them would be much appreciated. Thanks.

i don't think it's a z mark. notice the dot and tail on one of your pics. i think they are fish . the dot is the eye. sort of like the ying and the yang .
