• 单选题 Questions 11 to 15 are based on the following passage or dialog. Time passed and my cards sold well. My enthusiasm for the greeting card business grew quickly. All along, I had been drawing fantasy art: monsters, dragons, castles, etc. With the birth of my first son in 1980, the content of my work went through a pretty dramatic change. Fantasy went out of the window, and I began to illustrate reality. In the spring of 1983, we, The Mary Engelbreit Greeting Card Company, took our 12 little designs to New York to exhibit them at a national card show. I remember how big the show was. I just couldn.t get over it. I had no idea there were so many different card companies. And it was exciting because our 12 little cards were getting a lot of attention in that huge place! I.ve been told one of the reasons we had so much success at that show is because my card style was different than anything else at the market. I typically draw complicated details and use deep colors and funny or meaningful quotations. By 1985, many greeting card publishers started noticing my art, and two of them approached me with licensing contracts. I have always believed if you choose a job you love, you.ll never work a day in your life. If you ask about the mystery of my success, all I can say is this: to imagine is everything! 11.Before the birth of her first son, Mary Engelbreit.s cards focused on . [ 2.2 分 ]
