I could use any information anyone has about it.
Józef Chełmoński: "Czwórka"
The name of the painting is "Czwórka", it is an old word that means something like "The four", as in the four houses pulling the carriage.
I am completely going to guess this next part, but like the surname "Smith" comes from being a black smith, perhaps the surname "Czwórka" comes from being a horse and cart driver?
I don't know if that helps at all but since you have been searching for 3 years, I thought it was worth a mention.
Best of luck.
