Those wonderful portraits were shot in Sweden on November 1932 by J.E. Jonsson. John Erik Jonsson (1901 - 1995) was a co-founder and former president of Texas Instruments Incorporated. A skillful businessman, he became mayor of Dallas, a major factor in the creation of DFW airport and a philanthropist in later years.
No further info could be found why he photographed GG but we are working on this.
