Background information: This is from National Geographic’s Jan. 1929 issue, from an article that covers the adoption of the Latin alphabet in Turkey.

At the time, these posters were distributed widely, posted in shop windows and on the streets so everyone would grow accustomed to and learn the ’new letters’ quickly.

I’ve searched most online sources but couldn’t identify them (neither the serif nor the script). I guess a human element is needed here. I’ll be so happy to hear any suggestions. Thanks a lot in advance.
