I review orders at work and one customer's order many months ago immediately sent me to eBay to rectify a hole in my collection. A huge chunk of the order was 1962 Mars Attacks and while I obviously knew the set decently well, looking up prices on so many of the cards also gave me the opportunity to look at the images once again. It is such a visually-stunning set and was so far ahead of its time that I knew I needed to nab one or two for myself.
I went the mid-grade route and couldn't be happier with my purchases.
