Eagle-eyed viewers have spotted an eyebrow-raising sticker of Jill Biden in the foreground of a picture of the former president.
Earlier in May this year, Joe Biden's office announced the 46th president of the United States had been diagnosed with an aggressive form of prostate cancer that had spread to his bones.
Last month, the 82-year-old had skin cancer surgery called Mohs surgery, which cuts away at skin until no evidence of cancer remains.
Now, he appears to be recovering well as his daughter, 44-year-old Ashley Biden, a social worker and activist and mental health advocate.

She shared a snap of her father sitting at her desk in a surprise visit.
In the Instagram story, she wrote: "Someone came to visit me today! Working from home with Dad."
However, viewers say they have been left perturbed after spotting something 'insane' in the foreground.

Three stickers are visible on Ashley's laptop, including feminist icons, Frida Kahlo and Beyoncé, alongside another one of her own mom, 74-year-old Jill Biden.
The gigantic sticker of Queen Bey has ruffled some feathers as it remains plastered over almost the entire trackpad of the laptop.
Yet that's not entirely what viewers have taken issue with, pointing out that the sticker of Jill includes a somewhat tongue-in-cheek reference.
It reads: "It's Jill, Dr. Biden if you're nasty."

The college professor, who received her Doctor of Education in educational leadership from the University of Delaware, has long come under fire from critics for her title.
Following her husband's cancer diagnosis, President Trump's son, Trump Jr, lashed out in an apparent jibe at her doctor status, appearing to confuse her with a medic.
He wrote: "What I want to know is how did Dr. Jill Biden miss stage five metastatic cancer or is this yet another coverup?"

While dozens pointed out the former first lady is not a medical doctor, since she has a PhD in education, Trump Jr later claimed his post was 'sarcasm.'
Still, it's apparently become a bit of a family joke amongst the Bidens, though viewers say the sticker is 'insane' for her daughter to have plastered on her personal computer.
"Everyone talking about the trackpad but wtf is this," said one who zoomed in on the Jill sticker.
"No deada**," replied another. "Having this freak a** sticker of your MOM is next level creepy."

A third added: "As a 44-year-old woman, having this sticker of her mom is a wild choice."
However, dozens of others said it was a nod to a Janet Jackson song, 'Nasty', which famously has the line: "It's Janet... Ms. Jackson, if you're nasty."
"For younger folks on this post, this is a VERY well known reference in line to Janet Jackson's song 'Nasty,'" explained another.
