1st set (Type-based): All these covers reference the famous Stanley/Stella scene (if have yet to see it, check out this link: http://www.youtube.com/watch?v=S1A0p0F_iH8)
2nd set (Image-based): This set references the ominous bare light bulb (my apologies to the squished one, not sure how that happened)
3rd set (Non-computer based): This set is hand-drafted type, cut out with an exacto knife and held up to a lamp with a textured shade. More refinements to come with this.
One last note, feel free to comment! I have finally figured out to read and comment back (thank you to Marilyn Buel for suggesting that I solve that problem). I always love to hear your thoughts and opinions!
