A few years back, I started a series called City Monikers, based on the nicknames of cities. For some reason, I included Brooklyn in that series. Being neither a nickname nor a "city" the way the other cities in the series were, it may have seemed out of place.
But, it was pretty much just the way I work. The idea was to do all 5 boroughs, and make that a subset of the Moniker series.
I have finally done that with my newest wooden block piece. I also have a version with almost no color that will be available later.
