Famous Croats and a Goldfinch

Another sorting center postmark I assume. Looks a little too nice for that. On the right is a European goldfinch from a 2022 Birdpex set of four stamps. And on the left is a pair of famous Croats from a 2023 set of four: film producer Branko Lustig on the left and writer and journalist Miljenko Smoje on the right.

Looking at the postmark... I can't quite make out where it was postmarked. Some central processing center I guess. The stamps are a butterfly set from 2023. From left to right, Marsh Fritillary, Poplar Admiral and Southern Swallowtail.
