In terms of sheer area, the slogan/banner for the Swiss #UBI #referendum, "WHAT WOULD YOU DO IF YOUR INCOME WERE TAKEN CARE OF?", was mind-bogglingly big.

Was designed to be read from #highrises.

The slogan was not very effective, despite its size.

(#UBI is just a #basicIncome to allow #subsistance - people are free to earn #wages to supplement that amount. Interestingly, the #bureaucracy in #Australia surrounding #supportPayments is said to almost be enough to provide a UBI!)
