Between the years 1970 and 1982 Bob painted under the names William Burkard and M. Frost.
Signing his name as either WB, Burkard or Frost.
The paintings all in oil created under the name Frost held a strong social and political view.
The paintings created under the name Burkard were all private commissions in thick knife oil and acrylic of a apocalyptic theme.
During this same time Orsillo worked as a fine art and commercial fashion photographer in Boston and New York.
The use of different pen names gave him the creative freedom to work and experiment in many directions at once. Since 1982 all his work is created under his given name.
