A New York City auction house is putting up for bid a parcel of jailhouse letters from notorious South Boston mobster boss and murderer James “Whitey” Bulger, including one where he signs off by writing “if you want someone whacked, give me a call.”

The letters, written to a woman identified only by the name Jackie, are being auctioned off in an online auction by Lelands. Bids will be accepted through Dec. 6.

So far, there had been just one bid offered, for $200.

There was a time when an offer from Bulger to have someone killed was not just small talk.

Bulger, one of the most notorious crime bosses in Boston history, was convicted in 2013 of 11 murders. He was implicated in but not convicted of at least 8 others.

There is no date on the three letters, but they appear to have been written in the final years of Bulger’s life. Based on clues in the text, they appear to have been written sometime between his his November 2013 conviction and sentencing and his being beaten to death by another inmate on Oct. 30 of last year.

One of the letters fondly recalls the period from 1994-2011, when he was on the run with girlfriend Catherine Greig, as “a 16-year honeymoon" and “the best years of my life — longest period without any felony — no robbin (sic) banks or killing anyone.”

The letters refer to actors Jack Nicholson and Johnny Depp. Nicholson played a Bulger-based character in the 2006 film “The Departed.” Depp played Bulger in the 2015 film “Black Mass.”

Each of the letters bears the signature James Bulger, followed by “1428AZ," which was his inmate designation from his time as a prisoner at the famous Alcatraz federal prison in the San Francisco Bay.

Bulger refers to Alcatraz, where he was an inmate between 1959-62 before a transfer to Fort Leavenworth, Kansas, as “my alma mater.”
