The Ozmapolitan is a scarce Reilly & Lee publication only sporadically released. It’s short, generally only 4 pages, and filled with Oz quips and news as well as advertisements of current Reilly & Lee releases.
This Ozmapolitan from 1965 (Vol ZZXLX) advertises Sky Island and has a separate ad for the white cover Oz books, including the R&L release of Sea Fairies and Sky Island. I especially like these issues because they say “Wonderful Books of Oz” on the rear cover!. Four packed pages. In good condition with light age toning and fold marks.
