To answer a few questions...
The piece was created in Photoshop... I do use InDesign, but not on this particular piece... lots of layers... and I drew the middle in Photoshop with a Wacom Tablet...
LOVE Magritte... so there's that.
I thought (when I created it) that it was in the Public Domain... turns out the problem was with regards to using images of Mays and Mantle... but that got resolved (not sure how, as I wasn't part of the discussion)... The poster was a give-away at the time and that may have been part of the answer, as well... taught me a lesson about that... I do my own original illustration work, but I thought it would be cool to use my favorite '50s set as a border... I think I have to go back further in time, next time...
Here's another example of the kind of work I do... more illustrative stuff...
