London : The 'Usual Tourist Shot'

Three photos taken on quick trip to North and South Embankments of the London River Thames -- I lugged 2 Pentax 6x7 bodies and various lenses , filters etc and found most of my 1980 6x7 MU Mk 1 shots were out of focus except for these 3. I used E6 slide on my 6x7 Mk II so hope they will be better
