We construct a family of upper semi-continuous set-valued functions f:[0,1] → 2[0,1] (belonging to the class of so-called comb functions), such that for each of them the inverse limit of the inverse sequence of intervals [0,1] and f as the only bonding function is homeomorphic to Ważewski\u27s universal dendrite. Among other results we also present a complete characterization of comb functions for which the inverse limits of the above type are dendrites
