That makes sense - I thought about a lot of responses here but re-reading and thinking about it, it's at least ethically and intellectually neat and tidy (caveats to follow). Please bear with me as I wind down my own tortuous mental path; expert in similar but not identical subject matter.

I just want to make sure I hew to the absolute spirit and letter of the law on this one; I don't know anything about the provenance of this and don't know if I'd be taking money out of the artist's pockets by doing this.

My concerns are as follows and let's go with a random safety diagram rather than the funny dog thing for the sake of a better constructed chain: the artist published it on the internet so presumably printing it out on a piece of paper and pinning it to your office wall is probably fine? (? = ignorance for the rest of the way); laminating it and making company-wide safety thing is ? and probably no - copyright is there; it's not derivative to just post it as part of a safety thing. The mug thing is almost like printing it and putting it on your office wall. However, this time you've sent it to a 3rd party to do that. Any difference?

It's just interesting to me how copies proliferate and at one point, we're looking at an interesting thing on the web and the next it's all over even ostensibly for private use.

I dunno - this not-direct-analog (nothing to do with copyright so different standards and rules) comes up all the time for me and we barely get it right ever. I really appreciate the reply and if you have some time to expand on it, would be grateful :)
