YOU'VE been treated to numerous line drawings on urban themes.
Cityscapes, townscapes, looming cranes, congested traffic...you've been offered the lot over the last two or three years.
An office block under construction inspired this whacky image of a skyscraper taking shape, with girders, joists and panels pushing it higher and higher.
It's called Building a Skyscraper. No surprise there, then.
