Well, I'm glad I found this forum. I have been doing printed props for films, TV and commercials for over 25 years and I was checking out some of the stuff from the Shawshank Redemption. I remember getting a call from the prop master for the film back in the early 90s. He was looking for someone to help him produce the graphics, printed pops, etc. A lot of the letters had to be handwritten and, since I was schooled in France, my writing ended up being used for a number of letters, including the one Red reads at the end of the film. Yup, that's my handwriting there... It's nice to see that the production has reached 'cult' status. Kudos to Frank Darabont, the actors and the entire crew who worked so hard to make this production what it has become today!
I'm retired now but count more than 100 productions of all sorts that I have supplied printed props for.
