The front of the invitations were designed to replicate the old horror comics that i remembered as a kid. I always loved the old gory, spooky stories that came out of the EC publishing and the copycat books that Marvel and DC put out. So the invitation was designed to pay homage to those great sppoky books of yesteryear. I doubt that a single kid "got' the theme, but maybe a parent or two noticed the resemblance to our childhood comics.
I wanted the front of the invitation to really convey the sense of creepiness that i hoped to interject throughout the party. The Blurb both sets the mood and the theme for the party. The invitees should understand what the party is about after they read the front. I wish I could claim the art on thi side, but it was found by doing a search on the net. I'm not sure who the artist/photographer is, but I absolutely love the work.
The back of the information provided a more detailed account of the storyline and what the kids should expect from the party. Hopefully they understood that this wasn't going to be the typical costume party that they may have been used to. The instructions also explain why each participant was given a diary page, and contain a note to the parents stating that the kids will sometimes be outdoors and that the "pre-party movie" will be rated PG-13.
If you want to create your own invitations based upon my own, I have placed the text for both sides that you can just copy and paste into your own layout software. the text appears below the images.
