He was a guy about in his 50's and I didn't ask him too much but he lived and grew up in Baltimore his whole adult life. Collected in the 70's as is pretty obvious. His price guides go back to #6 and up to 20 so he probably collected for 15 years. He mentioned knowing Geppi and buying comics from him early on while Geppi was just starting. There are maybe 6 Golden Age books but the rest are Silver and Bronze. He was both a completionist and a specualtor for fun typical to what led up to the 90's craze. He was not as fussy about condition when he had to buy back issues. He probably completed those too but it looks like he sold off the Early Silver. With a few exceptions like ASM1; Spidey run starts at issue 103, FF at 40, X-men at 7, Avengers starts at 2, JIM at 85, but there are some holes. There are also inexplicable breaks, as a run of Thor goes to Issue 320 but FF stops at issue 99.
There are 3 long boxes of #1 issues with multiple copies in sets of 5 or 10. Just off memory there are 10x Wolverine 1-4, Ms Marvel 1, Teen Titans 1, Howard the Duck 1, Nova 1, 20x Dazzler 1. The 5x #1 issues for She Hulk, Spiderwoman, Spotlight 32, Premiere 38, Peter Parker, Star Wars, Star Trek, Arak and other DC,
Easy to imagine his mindset buying these and a decent forcast on his part. He skipped the Atlas books and most of the DC that came out during that time. Shoot he even bought doubles of the Hanna Barbaras.
He didn't buy horror, war, or westerns nor did he buy too many DC back issues and those he did aren't as sharp as the Marvels. He did buy some DC keys.
I don't know his occupation nor why he sold other than that he was a huge pack rat and his townhouse was a total mess of stuff. He kept all his middle earth type collectibles including a Lord of the Rings Animation Cel. I only mention that since it was clear both he and his wife were happy to "get rid of the stuff" and yet he did keep quite a bit which I would have gladly bought.
He did know their value but didn't want the hassle of going through them and selling them. It looked like he hadn't touched them since the 80's. I paid a reasonable amount in the thousands and the only sleep I lost from this deal was staying up late late going through the comics.
