This is a rather alluring Dutch telephone card from December 1995. I cost 5 Guilders (remember them? 5 Guilders is about 2.27 Euros at the exchange rate at the time of conversion).
One side of the card features a montage of the rear wheels of a mountain bike and a road bike, with half of the derailleur of each featured prominently in the middle of the card. Both look like Shimano models - although I have not taken the time to try to work out which models they are. Even obsessives have to stop somewhere.
