The SPD publishing house Vorwärts made an embarrassing faux pas when it sent a letter inviting the late cabaret artist Dieter Hildebrandt to an annual summer event, wrote the WAZ newspaper on Tuesday.
Hildebrandt, who died of cancer in November last year aged 86, appeared to take the mistake in good humor, however.
By way of an RSVP, the party received back their template fax with a cross in the "No, unfortunately I can't make it" box.
A handwritten note next to the box read "because I, Dieter Hildebrandt unfortunately died on 20th Nov. 2013. Warm regards, the widow."
"Clearly Mr Hidebrandt was still in the mailing list because he had close ties with us for many years," said Nicole Stelzner, organizer of the Berlin-based publishing house's summer party.
Hildebrandt rose to fame in West Germany in the 1970s and 1980s as the presenter of televised cabaret shows.
From 1980 until 2003 he presented the long-running ZDF show Scheibenwischer (Windscreen Wiper) which remained on air until 2008.
His widow is German actress Renate Küster, whom he married in 1992.
