Help with a locket please

Second piece is the locket. When I look at the little girl on the front, all I can think of is Alice in Wonderland. The picture is under glass. I don't think it was hand painted. The chain is 17 inches with a older clasp (thumb ring or sport ring?). Is this piece from the 1930's? What about the little girl, unusual or could it really represent Alice? Any opinions or suggestions would be welcome. Thank you again for looking and help.

 

yep

 

My goodness! Thank you Marote!

 

A modern version

As above. It's one of the Tenniel illustrations. Didn't realize it had been reproduced so widely on jewelry.

The clasp on the chain is a sport ring, so 30s would fit, but those were used into the 50s.

 

The chain is only 17"? What size is the locket?

One to make you bigger,
an' one to make you small,
an' the ones that Mother gives you
don't do anything at all...
go ask Alice, when she's ten feet tall!

 

The locket is 1 1/4" long and 3/4" wide. It's possible the chain is not original to the locket. The clasp is throwing me as it is an older style.

Ah, good old Jefferson Airplane, now Jefferson Starship I believe.

 

Alice took the chain off too soon, and it didn't grow back to its original size...

 

The locket appears exactly like the modern one currently available on Ama*on. As already said, the chain may not be original to the locket, so it's very possible that the locket is contemporary but it's owner was careless with it, hence it's look of "age".
Perhaps if we see the inside...?
