This is Malcolm appearing in a brochure designed by Professor Harold C. Bold (of the Department of Botany, The University of Texas at Austin ) for national distribution to the the Botanical Society of America to encourage college graduates to become botanists

It is clear from this brochure that botany is not just a science dealing with how to care for potted plants!
At the time, Malcolm was an undergraduate student majoring in Botany at The University of Texas at Austin (1960)
