Actually, perhaps the Gwulo guys and gals can help me out - I'm looking for an old photo which includes 218 Nathan Road (almost directly opposite the Shamrock) right next door to Tak Shing Street. Have no idea if such a photo exists but I guess any shot of the general area may include the building, it looks as though the two photos from the top of the Shamrock aren't quite close enough though.
It's the Four Seas Building now, but in a previous life it was a tenement where Bruce Lee lived from 1941 onwards.
