I made 3.5 x 5 inch baseball cards of two Cuban players who are now in the U.S, Yasiel Puig and Yasmani Grandal. They were a big hit with the kids and an even bigger hit with young men. A great icebreaker too.
John Barclay brought a Fujifilm Instax camera (think Polaroid).
On this occasion we were visiting the village of Cojimar, Hemingway’s old hangout. I walked up to a group of young men and sat down beside them. I passed out some cards and we were instant friends. John then photographed them with his Instax. When the images started to appear on the prints, their reactions were priceless. Great idea John.
