That's interesting, Pizzanini and its logo(s) - plural. As you can see from the photo above, there is PizzaNini (with baker and slice of pizza - and without), there is an adaptation for something called "Leonardo's Pizza" where Pizza Nini becomes two words and there's the newest incarnation of Pizzanini (or rather all caps PIZZANINI). This is not an isolated case mind you, Anthony's in Antelias has three logos cohabitating peacefully. Several other brands, depending on the whim of the art director, the printing press, the available material, the investment already one in one branch over the other, heck ever large corporations face it - when I asked a widely present company about their rebranding they admitted that it would take at least 2-3 years for the bags to catch up - "we ordered so many with the previous logo that we keep using them". The pizza is good though if you want to know!
