I'm a fan of the team jerseys of my youth (1960s/70s) and I have a small collection of retro jerseys. Where possible I have the matching cap.
When I rode the Eroica Britannia I went to a lot of trouble to look like the 1973 TdF winner, Luis Ocana. Correct coloured bike, Bic jersey and cap. Much to my disappointment no-one among the thousands in the event noticed, even another rider in a Bic jersey who asked to have a photo with me. When I asked him whether he was also a tribute to Ocana he just looked blank.
