Since we are on the Journey Into Mystery theme, here is a book I recently purchased in a nice trade/cash deal.
One of my fondest childhood memories was my mum taking me shopping to the West End of London when I was 10 or 11 years old. I dragged her into a comic shop called Comic Showcase, in it's original Covent Garden location, and spent ages staring at the amazing books they had on the wall. Although it was not my birthday or anything, my mum saw how excited I was and decided to spend £10 (a fortune back then) to buy me mid-grade copies of Journey Into Mystery #88, #96 and #100. With this purchase, I now own CGC 9.4 copies of all three of my all-time childhood gems.
