Featured 1888 locket Trench Art?

I picked this up as my daughters name is Alice and it looked like it needed a home!.
It's stamped 1888 and even though the silver has worn away almost completely you can still see the image of three men.
Someone has punched the name Alice on the other side. I did wonder about trench art?. Seems slightly odd to have a girls name with an image of three men?.
Do you think this locket started life as something else?.
I know it's of no value but I like to research what I can about it.
Thanks

 

The original "Three Men and a Baby>"

 

The front is die stamped,factory made for some type of celebration in 1888.

 

Brilliant. Lol, OH suggested I should look for the 3 musketeers!
Ok, so Russian. Definitely a locket or started life as something else?.

 

Locket,probably hundreds of them made at the time.

 

Not Russian - Prussian

 

Yes it opens easily. I'll take a pic in the morning

Edit- Just googled and once again @i need help looks like a winner!. Should be asleep but off to google more.

 

Looks like a later monogram done in a different style, if that means anything.

I started to enhance the monogram, but the marks below are so odd...

 

Anyway, i don't see trench art. But it is tantalizing

 

What is meant by "legitimation papers dog tag?"

 

Ok. I don't see much of a link between the 2 items other than the general shape and hinge at the bottom. I wouldn't put too much weight on that listing. I take it KSW's either does not open or had nothing inside?

 

souvenir of the Dreikaiserjahr.

Here you go

 

Could you give a size measurement, KSW? You said "locket" (which to me means pretty small) but comparison to that later piece makes me wonder whether it's actually larger than I expected?
