William Stout - T-Rex 'Dinosaurs' Dedication Sketch-1982

Here's a very cool vintage Stout illustration of a T-Rex (or Allosaurus...or one of those guys) dedicated to Pat Ortega According to WikiFur, the furry encyclopedia (yes there is one, apparently), I found this info on Pat:

Pat Ortega occasionally created furry-related work in the 1980's and early 90's, mainly as illustrations for American furry artists and fursuiter Robert Hill's Rowrbrazzle stories.

Pat Ortega was best known for her detailed reconstructions of prehistoric animals for the LA County Natural History museum. 

She has also done numerous book and magazine illustrations, as well as work for animation studios in the 1980's.

This was drawn on the inside front page of one of the slipcased limited edition copies of Stout's masterpiece 'Dinosaurs,' published by Byron Preis and Bantam Books in November, 1981.
