Mr. Skygack, from Mars

Mr. Skygack's comical misunderstandings of Earthly affairs gave Condo the opportunity to comment on and criticize social norms.

[2][4] Skygack subsequently appeared as a regular character in Condo's ethnic-humor comic strip Osgar und Adolf.

[5] 'Osgar und Adolf' was itself the basis for a theatrical production which included Skygack as a character; it was described by Gertrude Gordon in The Pittsburgh Press as a 'rousing good comedy'.

It also gave rise to the first recorded sci-fi cosplay when a Mr. William Fell was reported wearing a Mr. Skygack costume to a 1908 masquerade.

[2] In 1923, James W. Dean's syndicated column posited that 'Martian' characters with 'overdeveloped heads' played by Margaret Irving and Grant Mitchell in the film M.A.R.S.
