Hey Adam,I use to collect Mad Mag's too. I still have hundreds of them from the late 50's to around the early 2000's. My son reads them now and he now collects the newer ones as well as a lot of my old doubles. I can't remember exact dates anymore but I still have a straight set including Super Specials from the around the end of the 60's until I lost interest in collecting them around the year 2000. I couldn't walk past an old book store without going right through the place.
I'm planning on a meet some time in the coming months, if you can make it down to Albury then I'll show you. Hopefully I'll have the Genie by then and you'll have to see the Flash Gordon, it plays great.
