Visual-wavelength spectral comparisons around maximum brightness (arranged from top to bottom by decreasing peak luminosity) of the normal SN 2004eo (Pastorello et al. 2007), SN 2011iv, iPTF13ebh (Hsiao et al. 2015), SN 2007on, SN 1986G (Cristiani et al. 1992), and SN 1991bg (Turatto et al. 1996). The spectra of SN 1986G were dereddened using the reddening parameters of AV = 2.03 mag and RV= 2.57, while spectra of SN 1991bg were dereddened using the parameters AV = 0.22 mag and RV= 3.1. The grey shaded region highlights the 4150 Å Ti ii feature that is weak in SN 1986G, prevalent in SN 1991bg, and not present in the other comparison objects (see text for discussion).
