[2] Charles Revson, his mother's cousin and co-founder of Revlon, invited 17-year-old Selig on board the Revlon yacht Ultima II in Acapulco and introduced him to many guests that later became his lifetime friends, including Merle Oberon, Babe Paley, Gloria Guinness, Dolores del Río, Ahmet Ertegun and his wife Mica, Chito and Jeanette Jaffe de Longoria, Prince Egon von Fürstenberg, jewelry designer Aldo Cipullo, Vogue magazine editor DD Ryan, and publicist Eleanor Lambert.

[8] His skills as a spiritist and painter led to the creation of a unique codex titled Relaxatia, an ancient Solar Kundalini paradigm that he rediscovered through Purépecha Nahaulli high priests in Zihuatanejo, Guerrero, Mexico.

[2] Selig made commissioned portraits and works of art for Isabel Goldsmith-Patiño,[9][10] eldest daughter of Sir James Goldsmith and granddaughter of Antenor Patiño,[11] Prince Egon von Fürstenberg,[12] Catherine Oxenberg and Kelly Le Brock,[13][14] among others.

Exhibitions featuring Selig's paintings include "100th Anniversary of Hollywood - Portraits of the Stars" held at the Otis College of Art and Design in Los Angeles, and "Organic Landscapes" sponsored by Versace in Beverly Hills.

[15] He helped launch Hemingway's career in the 1970s, and established the initial marketing and public relations format that helped make her a global celebrity, introducing Hemingway to a circle of fashion professionals in New York City that included photographer Francesco Scavullo, designer Halston, Vogue editor Francis Stein and Marian McEvoy, a fashion editor for Women's Wear Daily.

[17][18] Several years later, Hemingway made Selig the creative director for her 1990 Playboy magazine cover and pictorial by photographer Arny Freytag that was shot in Belize.

[27] The early 20th-century Italian Renaissance style building, with its elaborately painted portico, ceiling decorations and frieze, was a former residence of silent film star Pola Negri.

[34] Friedeberg's 2013 Too Much is Not Enough exhibition at the Casa Diana Gallery in San Miguel de Allende featured Selig's Spiritual Guides series of paintings.

[38] In 2014, a portrait painted by Selig was featured in the exhibition Joan Quinn Captured at the Brand Library and Art Center in Glendale, California.

[39][40] A solo exhibition of Selig's latest Magic Talismans[41] series of paintings opened on April 1, 2015, at the Sollano 16 gallery in San Miguel de Allende, Guanajuato, Mexico.

The labor-intensive painting formula involved multiple transparent thin oil glazes, building layers applied with #000 sable brushes on egg-shell gesso, resulting in a deep, detailed and jewel-like three-dimensional finish.
