Deletion of 321 North Clark

Comment: It initially seemed non-notable, and almost all of the sources that turn up in a search are clearly  coverage of transactions, people moving in and out and so forth. These must be ignored for the purposes of this discussion. But I was able to find http://pqasb.pqarchiver.com/chicagotribune/access/24759104.html?dids=24759104:24759104&FMT=ABS&FMTS=ABS:FT&type=current&date=Apr+10%2C+1988&author=Paul+Gapp%2C+Architecture+critic&pub=Chicago+Tribune+(pre-1997+Fulltext)&desc=THE+ODD+COUPLE+QUAKER%2C+NIKKO+STAND+TOGETHER+IN+UNEASY+UNION&pqatl=google this Chicago Tribune article, which dwells on the building itself in a significant way. It's also discussed in http://books.google.ae/books?id=Gf1bAS6OxvYC&pg=PA40&lpg=PA40&dq=%22quaker+tower%22&source=bl&ots=z1elqvYZWs&sig=MSnVkQEmoy00iytKdKlfId2Phqo&hl=en&sa=X&ei=3uSAUNq3E8HLrQeEyYCwBA&redir_esc=y#v=onepage&q=%22quaker%20tower%22&f=false this book and http://books.google.ae/books?id=aQE21zTaju8C&pg=PA562&lpg=PA562&dq=%22quaker+tower%22&source=bl&ots=MsDikVI3ci&sig=ro72OnYJxfMqMLUju88LQ0MKp6s&hl=en&sa=X&ei=3uSAUNq3E8HLrQeEyYCwBA&redir_esc=y#v=onepage&q=%22quaker%20tower%22&f=false here, although briefly. Combined with the Tribune naming it one of the most important buildings of the '80s, as cited above, I think this passes . I suspect that there are other reliable sources covering the building, but that they may not exist online because much of the coverage appeared in the 1980s

Comment: 321 North Clark was the headquarters for The Quaker Oats Company. The  Quaker Tower in Chicago sold for $134 million, or $159/sf, in June 2001 which is when Quaker Oats moved out. By August 2003, its value was $225 million. The article presently has sourcing and add what is noted above and that results in the topic meeting . Being a big building located in crooked Chicago, there's probably a lot of write ups on its contruction and cost overruns, city difficulties, etc
