Looking at Elizabeth Perry's home page, I noticed that she contributed a drawing to a show now up in a gallery in Alberta: The 1950 Ford Show (officially entitled: "WILL 100 ARTISTS PLEASE DRAW A 1950 FORD FROM MEMORY.")
I've got some interest in '50 Fords and so did a bit of further exploration.
The site explains that the show is a response to a conceptual work by the artist Ed Ruscha of the same name. The curators asked 100 artists to do as Ruscha asks, using a sheet of 8.5"x11" office paper.
A staff member at the gallery, using the Flickr name pinkmoose. Has posted some shots of preparations for the installation:
Here's a contribution from one of the artists:
He says: "I’ve got a piece in an upcoming Rushca tribute show. The theme of the show is drawn from his conceptual piece Will 100 artists Draw A 1950 Ford From Memory. Essentially, the curator went out and found 100 artists to draw a Ford from memory. It didn’t have to be taken literally; I featured the interior in the drawing I came up with. Pretty happy with it, overall!"
This is Elizabeth Perry's '50 Ford picture (click image to view full size):
She says: "The text running up the side of the picture reads, 1950: Ford truck on the horizon nine years before I was born."
Here's a photo of the car itself:
