A good collection
This was one of the first comic book collections I got. I liked how I got to see some of the comics which are now out of print and REALLY REALLY expensive! This also started me on my way to becoming a fan of the Riddler. I liked the forward to this (how could you not, I mean its written by one of the best adaptations of the Joker! and Luke Skywalker!) it really expressed his opinion on the Comic world (or is it considered a Multiverse now? Well what ever) and how he enjoyed working and contributing to such a media such as comics.
I really like the Secret Origins special which is in here. I mean, It was well presented. It showed great versions of the origin of the Pingian and Two-face. I really liked the "When is a door" section. That was a cool set up. He sort was crazy and mysterious at the same time. Now that is how the Riddler should be like! I especially like the cover! It has good coloring and how the artist chose to show the characters really brings out their personality.
All and all; given the time period in which these comics were written (Pre-crisis) I would say that these were and are some great comics!!
