i am second guessing myself....is that terror tale that was mentioned an old scream castoff? or is it just a homage to scream?
I'd have to see the pic of Tharg which Conrad mentions before weighing in with my opinion. Seems quite a way after Scream! folded to dig the story out of the slush pile though.
Typing blind here, as I don't listen to the podcast (sorry), but if I recall correctly, the initial run of (four) Terror Tales all had a sign-off image of a skeletonized Tharg's head - could have been a Scream homage, or just a quirky way to differentiate the series from yer standard Future Shocks.
The image in question was drawn by Paul Marshall* (as was the series banner), in "Vintage Marshall" style.
I actually attempted to buy the original art for it from Paul several years ago, but he no longer had it.
*With the exception of the one drawn by Mick Austin himself at the end of his Terror Tale in Prog 840.
