How much could this miniature painting be worth?

I think that this is something that you would need to have appraised, unless there is an expert on Hummel collectibles and Hummel art here on fluther. A lot of Hummel stuff can be fairly valuable, though most of is not astronomically valuable, but like most everything else, whatever any individual value one Hummel piece might have depends on a lot of variables.

One thing you can do is to search for what you have on eBay and try to find something similar. That is sometimes a good way to determine something’s value but if what you have is either unique or you don’t provide the right search terms you may come up empty handed.

It really depends what people are willing to pay for it. I’m no expert on art, and a name really carries no weight with me, I don’t care if it is a Picasso or by some guy who sells paintings in the park, so I would never really pay that much for a piece of art. However, I quite like the dark and gloomy look of this particular painting, with that in mind, I would be willing to pay $100 to $150 for it.

You could inquire of the curator of the Berta Hummel Museum. You will probably want to photograph the image flat on a surface rather than vertical. Also the frame looks as if it is water damaged. Is the artwork water damaged in any way? If so, the value is severely diminished.

who painted it?

There are also some on-line appraisal sites you could submit the picture to. Wow! They had back packs in the 50’s? Very interesting.
