Mrs and Mrs Webb, a couple in England, were mailed this curiously sinister portrait. No return address, cover letter or other information accompanied the plain but very strange painting, whose subject was described by Mrs Webb as "a horrible old crone." Turns out that it's probably a rendering of Mr. Webb's great, great grandmother. [BBC]
P.S. Speaking of plain but menacing paintings, it appears that we've never covered The Hands Resist Him here at Boing Boing!
