Figure 1
At the top center is the label “Dr Esther Mahlangu”. Just below it is the title “Artwork explained using Mathematical equations”, and again below it is the statement that reads “Degree of Doctor of Philosophy in Mathematics (Honoris Causa)”. Beneath this text, at the center of the poster, is a rectangular framed artwork containing three horizontal rectangular panels stacked vertically, each panel displaying symmetrical geometric motifs, enclosed within a larger rectangular border. Below the artwork, multiple blocks of dense text appear arranged across the width of the poster, with paragraphs on the left and right and mathematical equations and symbols with explanatory content. Toward the lower center is a circular university seal, partially overlaid on the text. At the bottom, a watermark reads “U N I S A” in large size, with the text “University of South Africa” just beneath it. At the bottom right is a rectangular emblem containing a smaller version of the artwork, alongside the “U N I S A” and “150” anniversary marking.A picture of artwork of Dr Esther Mahlangu explained using mathematical equations (copy at Unisa Archives)
