The auction at Envy in Fitzrovia will raise money for the Red Cross. It has been organised by The Location Guide, the Advertising Producers Association, Getty Images, Audio Network, FilmLight and Envy.
Funds will be raised through a £10 donation on the door, a raffle and an auction for items donated by advertising agencies, production companies and members clubs.
The organisers welcome further donations to the auction, which already includes six bottles of champagne and cake from JWT, champagne afternoon tea for two from the Soho Hotel and a framed print from the Getty Gallery.
Separately JWT London has raised more than £1,000 from cake and prop sales, on top of $25,000 already donated by the global network.
Dare also ran a cake sale in collaboration with its EdC sister agencies Elvis, Brando, Band & Brown and Identica on Monday, which raised nearly £1,000.
DDB London staff also got baking over the weekend and collected more than £500, and Grey is holding a fund raising sing-along in its bar today.

Anomaly London has appealed for donations online with a project that incorporates their variation of a traditional Japanese story about a wish that may be granted to the person who has the devotion to fold one thousand origami cranes.
It has set up a website called Onethousandcranesforjapan.com, which offers instructions and designs of origami cranes in return for a donation. So far 358 cranes have been created.
