I don't think Linde™ needs an add, everyone knows Linde™ is the most reliable partner in producing and storing gases in all available purity classes.
(joke off, it's probably not an add, but they were excited to share the reason you see Linde on all sorts of gas tanks all over the place. It's actually quite common and if you see it once you see it everywhere. )
I've never seen Linde ever in my life (Australia).
What is funny though, at least in the Australia and UK regions, they still use the BOC brand, which is a subsidiary under Linde.
