63 . Leaf from the ledger of responsa of Rabbi Akiva Eiger, with his signature
Large leaf from the ledger of halachic responsa of Rabbi Akiva Eiger ztz"l, with his signature (apparently written by his son and successor, Rabbi Shlomo Eiger, Av Beit Din of Posen).
Specifications:  leaf. 22x37 cm. Light green paper. Text on both sides.
Background: Rabbi Akiva Eiger gave detailed instructions regarding the editing and printing of his responsa, including details regarding initial honorifics, corrections and deletions.
Unique features: The responses on this leaf have corrections to the honorifics of the addressee, per Rav Eiger's instructions to delete them etc. Signed at the end of the response: עקיבא in a square script. This seems to be the writing and signature of Rabbi Akiva Eiger that he used to note his approval to printing the responsa. He wrote in print letters so that they should be printed in print letters. (Refer to printed material with similar signatures.)
Content: There are three sections on this leaf. Two responses were printed in Shu"t Rabbi Akiva, first edition, sections 14-15, and the last section with novellae on Tracate Eiruvin was printed in Drush V'Chiddush.
The responses were sent to Rabbi Yisrael Lipshitz, author of Tiferet Yisrael on the Mishnayot. In the first response, Rabbi Eiger strongly opposes the Tiferet Yisrael's instruction to make an "eiruvei chatzeirot" without bread. The Tiferet Yisrael included a rebuttal in the introduction to Tracate Eiruvin.
Everything written above was seen and confirmed by Rabbi Shmuel Einstein ztz"l, author of Kitav V'Chotem and more, an expert on the manuscripts of Rabbi Akiva Eiger.
