Well, yes, I have found one, and there could easily be more.
In a recent dive through the stamping archives, I found this magazine:
Turns out, this early issue of Stamping and Papercraft had a project by Ellen Eadie.
Here it is :
It's a lovely journal cover, on a fishing theme. This looks like it was early in Ellen's career, she didn't even get a byline.
But, the instructions do show how to ink up a stamp with markers, and there's an illustration.
This, I am quite sure, is a photo of the very stamp I have for sale.
So there you go!
