You only need to concentrate on three words, you are clear on the others. The words are envelopes, glue and chalk. Well done!

"Kyiv landscapes appear in the Apple presentation - and not for the first time!"

Kiev landscapes appeared in the Apple presentation—and it's not the first time. Kiev landscapes appeared in the Apple presentation—and this wasn't the first time. //If these are headlines, this is fine. But if this is for formal writing I would write something like: Photos of landscapes from Kiev appeared in the most recent Apple presentation. This wasn't the first time they've been used.

What’s the headline for? To me “and it wouldn’t be the first time” sounds more interesting and thought provoking. However, if it’s supposed to be super formal, as you have written it, I would keep it as is but say “it’s not the first time”
