In 1926 and 1928, the first two volumes of Alexander Pushkin's Letters were published, covering the periods 1815-1825 and 1826-1830, respectively. Both volumes were edited with notes by Boris Lvovich Modzalevsky, a well-known Pushkin scholar and employee of the Pushkin House. The publications were published by the State Publishing House in Moscow and Leningrad as part of the series “Works of the Pushkin House of the Academy of Sciences of the USSR”. The first volume, published in 1926, contains Pushkin's letters from 1815 to 1825. The second volume, published in 1928, includes the poet's correspondence from 1826 to 1830. Both volumes are provided with extensive notes and commentaries by Modzalevsky, making them a valuable source for studying Pushkin's life and work. In 1989-1990, the publishing house "Book" released a reprint of these volumes in the series "Pushkin Library". These reissues have preserved the original texts and comments, providing modern readers with access to important historical materials. The signature of the editor Nikolsky is an additional rarity that increases the collector's value of the copy (specify details for collectors). A rare and valuable copy for bibliophiles, researchers and collectors of Pushkin publications!
