Actually it's a close-up from a real children's art globe.

When I think about certain sectors/industries where I've worked for nearly 10 years each, in marketing and icongraphy one rarely sees imagery associated with children-- engineering sector & huge sectors of law. Don't know about urban planning, architecture and landscape design.
This is getting off-topic, but I've had interesting chats with dearie who is by training a civil engineer, then left that profession onto other things. On the cycling infrastructure design,...it's a constant tension to make engineers and engineering technicians consider human factors when designing cycling infrastructure. Alot of formal training on human factors in engineering design is not given, and not surprisingly in civil engineering, transportation engineering, etc. So he knows how limited their formal training is, how conservative they can be..locked to technical standards.
No wonder why sometimes we end up with lousy road/path designs and configurations for cyclists. The human factor is sometimes forgotten. And that includes children at times. So within certain engineering folks, to bring up the issue of children, even the iconography it's just ...well....not ..cool, rational. And we know engineers like to deal with facts, rationale, logistics, repetitive empiracal evidence, etc. Human behaviour just does not fit a technical standard too neatly. And that includes children.
