Here's the first of 5 postcards from downtown LV. Not as old as the linen postcards posted below, but still pretty interesting.

Left side of street: Golden Nugget with old sign; Frontier Club; Pioneer Club with Vegas Vic on top.
In the middle: that little red light is a Phillips 66 sign on top of train station. (Plaza had not been built.)
Right side: Horseshoe, when the Hotel Apache was still upstairs; Boulder Club; Las Vegas Club with vertical sign.
