This may or may not be #6 in the series.
It is different in that it is urban, so whether it fits the series , time will tell, when more views are painted. It is certainly a view from a train, so it probably will be included in the same group.

Another charcoal study for a future oil portrait. Not too distant in the future, I hope! This is John, pictured in his (and my) favourite building. Glasgow’s Kelvingrove Art Gallery. This is where I learned what paint looked like up close. It is where I was introduced to Whistler, James Guthrie and Henry Raeburn. One of those places that no matter how many times you visit, something new catches your eye every time.
John is standing close to the balcony on the first floor with the Salvador Dali room behind his shoulder.
