Light question: Which name comes first on a billboard, Spence's or Crawford's?

My uncle told me about how they solved it in the past by mentioning an old movie called "Towering Inferno" where it starred Steve McQueen and Paul Newman who at that time were big stars of equal level. I saw posters on Google and it went: ---------------------- Paul Newman Steve McQueen That's neat. ---------------------- Errol Spence Terence Crawford

Its already done they have Spence vs Crawford , it was probably another coin toss.
