Not an advert as such but who remembers being blown away when the V brake was first shown on the Grundigs. This did way more than any ad could for Shimano.https://www.youtube.com/watch?v=ikxYIarCjfc
What a great piece of history, thanks for posting it. @Repack Rider does 1984 in the file name indicate the year the ad ran? I'll bet you've got piles of historical stuff to scan in the file cabinets
I definitely had this on my wall (If anyone can find a higher resolution version let me know) together with the Campag ‘Tools of the Trade’ ad previously posted.
