Eat the Rich UK yesterday of a couple of trips I made to custom car shows in the 1970s. My memories are hazy and I thought perhaps my dad took me and my brother... but I think it is more likely I went with a mate from school as my dad had no interest in customs!
Anyway, I was trying to work out when the shows at Olympia began, and here is a photo from the first custom car show in 1975. I'm not certain if this was the first year I went, but I remember the bikes more than the cars... a huge influence. I found the images here... some interesting snaps if you trawl through the links.
