I was thinking more, as you're planning to stick them on the wall, of going for paper charts in the first place.
Another source for those which you may not have considered, and which isn't expensive, is here:

I bought a set of high- and low-level charts a few years ago and they are very good quality.
Alternatively, if you really do want PDFs, try here:
