A billboard for Harveytiles, a roof tile concern that has billboards and ads up all over Lusaka. Many of them have a Christian theme, like this one. The flip side of this particular one says: "A roof without Harveytiles is like fire without flames. Remark: Even hell fire cannot destroy Harveytiles."
One question, though: If "only heaven is covered with Harveytiles," isn't that limiting to your business potential? So I can't put Harveytiles on my own house, just because it isn't heaven? On the other hand, heaven's supposed to be pretty big, so I can see how that one order could keep Harvey busy.
I think my favorite, though, is one on a roundabout on the east side of town. It says something like "Harveytiles: Coverage for heaven. Other tiles: Coverage for hell." Accusing rival brands of being on Satan's team! Cheeky!
