At the same time as the above, creative agent Emilio d'Antonio (representing Andy Warhol, John Cage and Robert Frank, amongst others) presented Allan to architect George Nelson, and through him began work on pavilions, displays and presentations for the 1959 American National Exhibition: with Charles and Ray Eames he designed presentations and media supports for Buckminster Fuller's 'Dome' project, and the same again for their "Glimpses of America" projections of 2,200 images onto seven large screens. Lastly, under the direction of Edward Steichen and the MoMA, he designed the supports for the "Family of Man" exhibit. After a six-month convalescence period because of a motorcycle accident, and still working with Nelson, he worked extensively on the design and presentation of the Synergetics "City of Tomorrow" pavilion for the 1962 Seattle "Century 21 Exhibition".
