In october 2012, the Estonian biggest confectionary company Kalev and Estonian national opera Estonia signed a sponsorship contract. The contract was signed in a day when Kalev gifted to Estonia a miniature model of national opera theatre building, which was made of marzipan. The sponsorship event went really successfully, it gained a lot of media attention and many coverage.
2012. aasta oktoobris sõlmisid AS Kalev ja Rahvusooper Estonia sponsorleppe, mille kohaselt sai Eesti suurimast magusatootjast rahvusooperi peasponsor. Sponsorlepingu sõlmimine toimus päeval, mil Kalev kinkis Estoniale teatrimaja väärika 100. juubeli puhul martsipanist hoonemaketi. Sponsorleppe sõlmimine saavutas maksimaalse meedia tähelepanu.
