The answer is yes, and here are two of them.
Professor Adam Arenson blogged about these in 2012, and for some reason I missed that post--even though he was kind enough to include link to this blog. I'm just going to highlight a few major points here, and you can go to his post to get all the details (and more pictures).
These mosaics are signed MSD, standing for Millard Sheets Designs, and were probably first installed in Los Angeles in 1974.
These mosaics were framed, and were later moved to different locations, perhaps Westminster, Santa Cruz, and Riverside. They ornamented temporary buildings while the permanent Home Savings & Loan branch was being built, and while its permanent, unique artwork was being created and installed.
Currently, they are installed in Irwindale, at the San Gabriel Valley Corporate Campus on Rivergrade Road. This site was the coporate headquarters of Home Savings and Loan from 1985 to 1988, and of Washington Mutual after that.
I blogged about another piece of at this campus, a mosaic fountain by Joyce Kozloff..
