In addition to creating hundreds of posters, logos, books, trade ads and illustrations, Wilkes designed such significant covers as the "invitation" iteration of the Rolling Stones' Beggars Banquet; George Harrison's All Things Must Pass and The Concert for Bangladesh; Cheech & Chong's Big Bambu; and Neil Young's Harvest and Homegrown.
Wilkes also produced and directed TV and radio spots, music videos, films, mixed media presentations and special events.
For the album's front cover, Wilkes used a confronting image showing a naked child beside an empty food bowl,[2] in an effort to bring home to record-buyers the plight of the refugees of the Bangladesh Liberation War.
"[2] According to Jonathan Taplin, who served as production manager at the Concert for Bangladesh, Apple distributor Capitol Records were concerned that the image was not commercial enough, but Harrison was resolute that Wilkes's cover should be used.
[4] In 2004, Wilkes discussed this cover image, and his involvement in Harrison's aid project, with journalist Matt Hurwitz of Goldmine magazine:[5] Wilkes along with his partner, Craig Braun, was awarded [Grammy Awards ] by NARAS in 1973 as art director for the 1972 Ode Records' version of Tommy as performed by the London Symphony Orchestra and English Chamber Choir with Guest Soloists.
