Even when the paperwork is completed, and even though many are highly educated, they struggle to find full-time work and are forced to continue making a living by selling artworks like these, watching over parked cars for tips, and by doing other menial jobs ill-fit for their education.
If you'd like to purchase one of these items, I always see the guys selling them at the turnoff to Kirstenbosch Botanical Gardens on the M3. They're not expensive, so unless you don't have the money, rather pay full price and smile. :)
