Separating the poster in two and using the bottom half for a reflection that reveals another version of the character seems to be a popular design choice these days. Outside of these two posters we also had the poster for The Life Before Her Eyes, which went in a similar route.
Of course, in the case of the posters above what is striking isn’t just the similar concept, which is actually a bit different since the one for Flashback uses the reflection to showcase the younger version of the character while the one for Leaves just shows a different version of the same person, but also the general visual resemblance.
I think that the poster for Leaves is the better one, mostly because it has less fat allowing the focus to fall squarely in the main concept. Secondarily, I prefer the strong green, strong black and white color scheme better than a like the similar but bluer scheme of Flashback, and making the poster work with either side up is a neat idea.
Is it turns out in Leaves of Grass Ed plays twins, so it’s not really two versions of the same character. But still, same diff, right? Right?
