RR Auction will offer the items Saturday in Boston.
Parker and Barrow were shot to death by lawmen in Louisiana in 1934 following a massive manhunt.
The auction house said Parker wrote the poetry in the bank book while in jail.
Other items being offered are a Bulova watch Barrow wore when he was killed, a draft of a Dallas police “wanted” poster for Barrow and a shotgun confiscated after a 1933 shootout in Joplin, Missouri, in which two lawmen were killed and the gang sped away.
