Prunier, from France, sells on 13 November 2016 as lot 158 a "Northern School, 17th century" Gardener, a small panel (21 by 19cm) with the engraving it is based on, estimated at 1,500 to 2,000 Euro.
RKD: surely the leaves on the trees are spring-like, not autumn-like?; I added another Vrancx, this time described as Spring, as comparison) or as a moralistic mocking of working people.
What the auction house doesn't say, and is invisible on their small images, is that the engraving is based on a Teniers painting. This could have saved me most work that went into this blog post :-)
The painting for sale is one of many copies after Teniers, and is charming but not particularly good or rare. It will struggle to get the estimate probably.
