"In the month of October 2015, the Institute published in Portuguese, a text with a selection of smiley clay figurines. Research continued and this book is the outcome of a splendid curatorship that resulted in a rich exhibition of the Secretaria de Cultura [] As a celebration, we have chosen to show a collection of magnificent pieces of clay known as "smiley faces" from Veracruz."
