I suppose it's possible that these posters can motivate a team, but only if everyone on the team knows and understands, on a deep level, what the slogans stand for. Unfortunately, it's very tempting to skip the part where you have a set of long, hard, emotionally draining conversations with the team, where the team puts measurements in place that help them see when they're not holding to their stated goals, where they get frustrated but keep trying to improve things anyway. Why go through all of that when you can just put up a poster!

(edit: My point is that these posters seem like they should be earned, not just purchased.)
