First Ned to say that the stamp on her doesn't look very pretty... Good you have another with no that ugly thing
The reason the stamp is on her leg is that when Schleich decided to add the address on their models, naturally the stamp needs more space. The new long stamp didn't fit under her foot so its on her leg.
The woman with no stamp on her leg is older, made before Schleich made their change. I guess its like that
I might be an awkward person but that's me and I'm not gonna change myself
