With this I hereby verify that the esrogim which are being distributed upon the instructions of my father, our master and teacher, Maran HaGaon shlit"a, by Kupat Ha'ir for the Tu B'Shvat campaign are esrogim that my father, our master and teacher, Maran HaGaon shlit"a made a bracha on during Sukkos of this year; of course we separated terumos and ma'asros from them according to halacha.
I am affixing my signature to this:
