The small block building in the background was at the junction with Waterloo Road (on the northern side of the road) but I have no idea what it was. Gwulo has a much clearer picture of it here, and I suspect the presence of a "telephone exchange" tag on that picture may be the explanation of what it was. Can anyone confirm?
Hong Kong Tiger Standard was the original name of the HK Standard newspaper, still in circulation but a sad shadow of its former self. The tiger in the original title came from the founder, Aw Boon Haw, who is more famous in HK for his Tiger Balm empire. The politics of the paper (and it's Chinese sister paper, Sing Tao) is now very much pro-CCP - a far cry from its early pro-Kuomintang stance. In fact, one of its former Editors-in-Chief is Robert Chow - a name familiar to a large "silent majority" of Hong Kongers who actually secretly want to punch him.
