I'm still not convinced. It's not the same twin tower design as the beer mat and a different brand name.
Going back to the Kingston Gleaner in Jamaica for a minute, it was being advertised as Tower Brand Lager Beer in 1929/30 (as per the Singapore advert) but just Tower Brand Beer (as per the beermat) by 1936.

Perhaps the product was tweaked to suit different markets?
