In the mid-1930s, this staid format slowly began to change into a more varied concept with a more contemporary look. In 1934, a series of stamps was issued depicting ancient and contemporary Indians engaged in activities such as making pottery. The frames of each stamp differed noticeably and the central image sometimes crossed over onto the frame. The lettering began to take on a more modern aspect also, such as a distinct Art Deco font on the 1935 stamp illustrating Zapata.
