This photo of a souvenir poster was given to those who participated in the filming of the film slated to be in Japanese theaters March 26th, 2016.

As shown on the poster above, the top of the poster says "Kamen Rider 45th Anniversary Commemoration Film" and the center has a photo of a re-arranged/re-designed version of the Kamen Rider 1 helmet covered by the text "Kamen Rider Ichigo(Kamen Rider 1)".
Another thing to note is that the Sakurajima color scheme(the very dark green and green color scheme that succeeded the dark blue and light blue colors when Hongo returned to the show) is being used.
