Nice to look at? For Sure! To learn? Depends on.

Well, first of all, let me say that the poster looks absolutely great when it comes to color matching, et cetera. In addition, the poster is not just the periodic table alone but (although small, but still!) Diverse background information with regard to the composition of air, the human body, the sea, and the earth's crust. The structure of an atom is depicted, which I personally find useful.
Otherwise remains to say that it's just the periodic table, and one (except the above mentioned supplements) no longer gets - except a beautiful, color representation. Anyone who wants to learn it, the poster has probably hang so that it really can look at it head-on, but here I recommend rather a formulary with the periodic table in the appendix.
To "look nice" in the room, it is okay in any case, who knows the panel, which helps the color display when he quickly an item does not take time, a glance so is enough! For all other of this poster is well recommended as a kind of "nerdy gimmick" in their own room!
