Sweet Vintage Gold Tone Cross Necklace on Original Card

Delicate little gold tone cross necklace.
The cross is 2.5cm long and made, I think, of brass.
Most of them are a bit tarnished but will polish up beautifully with a jewellery cleaning cloth.
The chain is 19.5cm long and there is a lovely old fashioned safety clip at the back.
They are old, probably 1940s/50s and found in an old warehouse - some of the cards are a bit foxed. If you are buying this for a present let me know and I'll send the best card I have.
Made in U.S.A printed on the bottom.
