Got an email today from the dutch cycling association because they are celebrating their 50th cakeday in which they shared a post with some of their old posters. Most don’t make sense if you don’t speak dutch, but they’re here: https://www.fietsersbond.nl/50-jaar-fietsersbond-campagnes-en-posters/
Edit: turns out they’re quite proud they made this poster and wrote a whole post about it in english. Not instead of the other url, but an addition for sure: https://www.fietsersbond.nl/english-info/whose-space-is-it/.
You can place a bike on either side of each bar. Look at the brackets for the front wheel.
