Role in modern comics and redesign
Dutch ComicsIn 1998, the editors of the Dutch 'Donald Duck' weekly magazine decided the three girls should be modernized, and they got permission from the Disney Company to do so. Dutch Duck-comic artist Mau Heymans designed a new hairdo and new wardrobe for April, May and June.
The new hairdo first appeared in the Dutch comic "Nieuwe Coupe". They now don't look the same at all in Dutch stories, and don't have the 'girly' occupations anymore they had when Barks created them. In some Danish stories, the new hairdo has been copied. The Dutch comics with the redesigned girls have also been published in other countries. However. They still appear in their old design in several other countries that haven't adopted this redesign yet.
While April, May and June still appear regularly in comics. Their roles are usually quite minor. The exception are the Dutch version of Donald Duck comics. They appear often in these. Together with Daisy in comics based on her or in comics called "Duckies". Which focus on April, May and June and Huey, Dewey and Louie.
In Italian comics they are called Ely Emy and Evy.

Who is Who
You can recognize the girls in their modern look: April (Lizzy in Dutch comics) has one ponytail in her hair, and wears red. May (Juultje in Dutch comics) wears a headband, and dresses in blue. June (Babetje in Dutch comics) has the two pigtails, and wears yellow or green.
When Don Rosa was asked if the mother of April, May and June is Donna Duck who appeared in a few stories before Daisy appeared, he replied that is a good idea.
