In downtown Joburg - Newtown to be exact - there is an outdoor media agency that is changing the outlook of townships in South Africa and beyond.
Founded and owned by a husband-and-wife team, Anisa and Kabelo Kale, Keys Communications has been in existence since 2009, specialising in mural advertisements.
Anisa, who worked for advertising agencies from 1992 to 2009, said being in that space was something she was comfortable with.
"I worked for a whole lot of big agencies, from telecoms to alcohol beverage companies, but for personal reasons we decided - together with my husband - to start our own agency. Firstly, it was because we needed flexibility, we have two boys, we wanted to raise them, to be there for them when they need us.
"Secondly, advertising is something we know best, we also wanted to give back to the community because we work directly with people that we rent out murals from. We pay them a fee every month, whether there is an advert on their wall or not."
Publicity specialist Anisa said they could have easily put up billboards but that would not be of benefit to the locals. So they decided on murals in order to benefit the owner of the wall.
