The Los Angeles Herald has an extensive article about the Wilson Block in the 8 August 1886 edition. The first paragraph says:
"In the Wilson Block, West First street, near the corner of Spring and between Main and Spring streets, Los Angeles has had another handsome addition to the needed accommodations for her rapidly growing business. The location is in ths heart of the city and of course one of the most desirable for business purposes. The lot has long been owned by Mrs. C. Wilson, and it is greatly to her credit that she has put up a structure which is not only an ornament to the city but one which will long be of substantial benefit. With the Wilson and Bryson Blocks rapidly approaching completion, the junction of First and Spring streets presents a lively spectacle. Both will doubtless soon be occupied from top to bottom."
