Abstract: The derivation of Feynman rules for unparticles carrying standard modelquantum numbers is discussed. In particular, this note demonstrates that anapplication of Mandelstam-s approach to constructing a gauge-invariant actionreproduces for unparticles the vertices one obtains through the usual minimalcoupling scheme; other non-trivial requirements are satisfied as well. Thisapproach is compared to an alternative method 0801.0892 that has recently beenconstructed by A. L. Licht.
