Yes, Montblanc has in cooperation with UNICEF carried out an eBay campaign running for about a month with celebrity autographs and used 149 fountain pens under the account montblanc_unicef_auction. The campaign was surprising, since Montblanc usually emphasises specialist-trade purchase and views eBay purchases rather critically. The charitable purpose and the high attention led to significantly increased bids, although they were mostly normal 149s. The hint of the auction was communicated via the Montblanc website.
