This is a file showing colour-coded plan and elevation views for brickwork in Double Flemish Bond of one and a half bricks’ thickness. In the elevation (that’s to say the right-hand-side-most diagram), heading full bricks appear in brown, stretching full bricks are in orange, heading three quarter bats are in green, and queen closers are in pale purple. The same colour scheme obtains for the plan diagrams (left and centre). Obviously if an actual pedestrian were viewing an actual wall, everything pale blue in the plans would -- from the vantage point of this pedestrian -- be hidden behind the face bricks, and can not therefore appear in the elevation diagram. A careful observer will note the wall represented by the elevation is longer than the wall shown by the plan diagrams. If the plan diagrams included a greater number of units, the 'L' shapes would appear rather thin. This thinness may risk making the pattern of units in the plan hard to discern, especially where the image is shrunk to fit a small area such as a spot on a Wikipedia page. If on the other hand the elevation includes only a small number of units, then the overall effect of an unbroken area of Flemish bond is hard to discern.
