WhatTheFont didn't help, neither did Identifont. I searched Typophile through Google, but I didn't find this (well, not immediately, anyway…). I did find out that they like using proprietary typefaces (other than Times and Minion, from what I found). Is [[http://www.edkashi.com/blog/uploaded_images/Christ_NatGeo_0609_cover-779...|this]] another case of a proprietary typeface at use? Here's [[http://lib.store.yahoo.net/lib/palemale-store/natgeodec2008cover|another sample]] and [[http://www.mandmglobal.com/cmsimages/Company-Profiles/National_Geographi...|yet another one]].
Thank you in advance!
