You mean there's no such thing as lowbrow? So says From Lowbrow to Nobrow (wikipedia.org):-
A book on literary culture written by Peter Swirski, professor of American literature and culture at the University of Missouri, St. Louis [...] Having gone through several printings, the book is by now a staple in American popular culture studies. It furnishes a series of analyses of the relation of popular fiction to high literary culture. In his work, Swirski challenges the highbrow vs lowbrow categorization of literary culture, and popular culture in general by focusing attention on what he terms the nobrow taste culture, whereby "authors simultaneously target both extremes of the literary spectrum".
What about these images?
Google image search on 'chess lowbrow'
The image in the bottom row, third from the left, is from Graffiti Pieces (May 2014) on this blog. The 'lowbrow' keyword is from How to Hold Chess Pieces (ditto; in fact, it's a video). It's just another example of Google applying a keyword to the wrong image; it happens all the time.
I wanted to make a new 'lowbrow' category for blog posts, but it looks like I'll have to settle for a 'nobrow' category instead. I can always change to 'lowbrow' later.
