The truck targeted football fans in the US city of Charlotte with a direct message: "Don't get vaccinated".
Beneath the stark white text on a digital billboard was the name and website of Wilmore Funeral Home.
The shocking targeted ad turned heads, as was intended, but all was not as it seemed.
The funeral home featured on the truck did not exist - and anyone visiting the website saw this message instead: "Get vaccinated now. If not, see you soon."
They were then directed to a service offering vaccines.
