I can't see the pic either, and the posted URL no worky neither.
There was a "16 Valves"
sticker fitted low down behind the door on 1.8 16v's, and I think also on earlyish 2.0 16v's. Various colours depending on colour of car. European
Cupra Sport's got a
sticker in roughly the same place saying "
Cupra", but we never got those in the UK.
