Yes, there is definitely a connection to Mexico, but I am not sure if the artist or artists are also from there. The whole theme of that place is about Mexico and there are frog statues, frog paintings, and everything is frog style. And those frogs are Mexican frogs who drink Tequilla and eat Nachos. They serve of course as well some Mexican food. I think it was maybe some people from the staff, who wanted to make it a bit more artful or maybe a graphic agency. Because there was nowhere a signature and you could find those comic paintings with the exact figures as well on the menu or on the doors to the toilet and just everywhere around. It's really a funny place, one day when we sood there for a drink, they even did a fire show on the street. Of course in frog costumes... :-)
