Hallmarked Mexican SS Angel Fish

[b][size=150]Hello Everyone,

I have just acquired some vintage jewelry and I am trying to find out as much as possible about the items. This one in particular is interesting. I know from the Eagle Hallmark that it was produced during the period of 1948-1980. although, I do not know who the artist is or what year exactly it was created. Any help and what it might be worth would be greatly appreciated!!

Thank you for your time in advance…[/size] [/b]
