Exhibit A

September 25, 2012

Board of Directors

Ladies and Gentlemen:

Since its founding over a century ago, the descendants of Jacob Sapirstein, and now the Weiss family, have guided American Greetings, including after it became a publicly traded company in 1958. After careful consideration, we have concluded that the best course of action is for American Greetings to return to its roots. Accordingly, on behalf of certain of the family-owned Series B shareholders, we propose to acquire American Greetings at $17.18 per share, net to the seller in cash.

We believe that $17.18 per share is a compelling price and that American Greetings public shareholders will find this proposal attractive. This proposed price represents a premium of approximately 20% over the price for the Class A common shares as of September 25^th at approximately 2:30 pm. It also provides the public stockholders of the company with liquidity and certain value in a highly volatile period in the equity markets.

We presently expect that the various foundations and related entities and certain members of the family associated with the company would reinvest or rollover all or substantially all of their shares in the acquiring entity, and that we would obtain debt financing to fund the balance of the transaction. We anticipate maintaining intact American Greetings employee base, which we view as its most important asset, and current senior management. At this time, we have not secured binding commitments for the required financing. We are, however, confident that such financing can be arranged based on current market conditions. We are informing you of our thinking at this time so that all shareholders are aware of it as we seek to finalize these arrangements and you have ample time to consider it.

We recognize that the independent directors will need to separately review this proposal under such process as they determine to be appropriate. We will keep you apprised of material developments and cooperate with you in this regard. As you consider this proposal, you should know that the Series B shareholders on behalf of whom this proposal is made believe that their ownership in the company is a strategic investment and have no current intention to sell all or any significant portion of their shares.

This proposal is subject to the finalization of financing, including the entry into definitive agreements by the sponsoring shareholders and arranging and entering into definitive

debt financing documents, the determination by independent directors that the proposal is fair and the negotiation and execution of definitive transaction documents. As we trust you will appreciate, given among other things the volatility of the capital markets, we reserve the right to withdraw or modify this proposal.

Thank you in advance for your consideration of this matter.

Very truly yours,
