  We experimentally demonstrate electromagnetically induced absorption (EIA) in
a vee + ladder system. The experiment is done using the low-lying energy levels
of $^{87}$Rb. A theoretical model of the system is made that reproduces the
experimental results. We study the dependence of the characteristics of the EIA
resonance on various combinations of the different control powers. We also
explore the contribution of various incoherent phenomena that affect the EIA
signal.
