I was referring to other signs in this gallery (for giraffe and something else that I've forgotten) that thanks God for various features of the animal. I was merely commenting on the vastly different tone and style of this sign (which is excellent).
Right i posted those you mean the ones for the White Rhino and the Giraffe as far as i know they are the only ones they did them for at least i`ve not spotted any others on any of my visits.
