Yoko Ono has taken a firm stance on gun control laws with a shocking image posted to Twitter this week.
Among several messages posted to the social media site on Wednesday, the most poignant of Ono's tweets included a photo of what were presumably John Lennon's glasses.
"Over 1,057,000 people have been killed by guns in the USA since John Lennon was shot and killed on 8 Dec 1980," Ono, who was married to the late Beatles member, posted to Twitter.
The message also included a photo of what appears be the bloodied spectacles Lennon was wearing at the time that he was shot by an obsessive fan in New York City over 30 years ago. The image reveals the glasses on a ledge with the skyline of Manhattan in the background.
Lennon was shot outside of his home, the Dakota apartment building, in which Ono still lives today.
The post Wednesday marked what would have been Ono and Lennon's 44th wedding anniversary.
Another message posted by Ono included: "The death of a loved one is a hollowing experience. After 33 years our son Sean and I still miss him. Yoko Ono Lennon."
The 80-year-old widow also called on famed filmmaker Michael Moore, whose projects include "Bowling for Columbine."
"Michael Moore #mmflint Join me to kick off a mass movement against gun violence from your living room on Sat March 23- Yes! Love, yoko," she wrote.
The active octogenarian is well known for speaking her mind, and just last month, sounded off in an anti-fracking campaign against Gov. Andrew Cuomo.
Ono married Lennon in 1969 just weeks after legendary singer's divorce from Cynthia Powell was finalized. She has often been named among the factors that caused the Beatles to disband in 1970.
Today, the only remaining Beatles are Ringo Starr and Paul McCartney; as Lennon was murdered and George Harrison died of lung cancer in 2001.
