Are these made by same artist?

These 2 figures have similar marks, are they made by the same artist?

 

Not my area of expertise, but to my eye, other than what looks like 18 on the bottom, they look completely different. If I'm reading the photos correctly, the putti are glazed while the piano baby is bisque; the piano baby has a conspicuous mold seam. Large commercial potteries do make a variety of ceramics, so differences do not preclude same maker. However...

 

I would say no they are not.

The putti are much nicer - notice how well the hands and feet are done compared to the "piano baby".

I do think they both came from the same general area. Germany or Austria.

 

It’s just odd that yes, they both look like they are marked with what looks like an 18. So the first one is what you call a putti and the second a piano baby? I’m attaching a picture of the back of the first one.

 

So is the putti piece considered a vase?

 

What they called a spill vase.

What is a spill vase?
A spill vase is a small cylindrical vase or wall-hanging vase for containing splints, spills, and tapers for transferring fire, for example to light a candle or pipe from a lit fire. From the documentary record, they probably date back to the 15th century. Aug 18 2018

The first number is incised under the glaze with a painted number over the glaze that probably references the decorator.


The other unglazed number is also most likely a decorator's number.
The one on the right looks like 78 not 18. The two eights appear to have been written differently. Hard to tell - too small.
