Ladies and Gentlemen:

We are acting as counsel for American Greetings Corporation, an Ohio corporation (the “Company”), in connection with the issuance and sale of $225,000,000 aggregate principal amount of 7.375% Senior Notes due 2021 of the Company (the “Notes”), pursuant to the Underwriting Agreement, dated November 16, 2011 (the “Underwriting Agreement”), entered into by and between the Company and J.P. Morgan Securities LLC, acting as representative of the several underwriters named therein (collectively, the “Underwriters”). The Notes will be issued pursuant to an indenture (the “Base Indenture”) to be entered into between the Company and The Bank of Nova Scotia Trust Company of New York, as trustee (the “Trustee”), as amended and supplemented by a supplemental indenture (the “Supplemental Indenture”) to be entered into between the Company and the Trustee (the Base Indenture, as so amended and supplemented by the Supplemental Indenture, the “Indenture”).

In connection with the opinion expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of such opinion. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, we are of the opinion that the Notes, when they are executed by the Company and authenticated by the Trustee in accordance with the Indenture and issued and delivered to the Underwriters against payment therefor in accordance with the terms of the Underwriting Agreement, will constitute valid and binding obligations of the Company.

For purposes of the opinion expressed herein, we have assumed that (i) the definitive terms of the Notes will be established in accordance with the provisions of the Indenture and (ii) the Trustee will authorize, execute and deliver the Base Indenture and the Supplemental Indenture, and the Indenture will be the valid, binding and enforceable obligation of the Trustee.
