I have designed many alphabets,
including Arabic, Cyrillic, Greek, Scripts, Zapfino, the Zapf Dingbats etc. etc.,
but my favorite typefaces are Palatino, Optima and Melior.
Unfortunately Palatino holds worldwide this sad record to be the most copied typeface.
Don't use Palatino or other designs offered cheap under obscure names or as similar designs.
Take the authentic original designs which you can get only from Linotype GmbH.
If you want still more to know, please see my publications »About Alphabets, Some marginal notes
on type design« M.I.T. Press, Cambridge/Mass. (1970) or »Hermann Zapf & his design philosophy«
selected articles and lectures on calligraphy and contemporary developments in type design,
with illustrations and bibliographical notes, and a complete list of his typefaces«
