"But I bet you didn't know that Key Bank and Puget Sound Bank were both once owned by Evinrude Motor Corporation."
Well, suddenly acquiring that little bit of information certainly stimulated my Johnson! :-D
Yeah, Key bought out PSB, off the top of my head, (don't even ask what a Bank was doing on my head) back around the early-mid '90's.
The WS Branch of Key migrated a block west, and the 4th & Union Branch Downtown migrated about 1/4-1/2 half block south from its location in the 1411 4th Av Building, where it had long resided, going back to the old Seattle Trust days.
Back around 1986-ish to 1987-ish, Puget Sound Bank became a major tenant of the originally named Washington Building, and the Building was renamed Puget Sound Plaza.
The Bank also took over the 4th & Union corner spot that had housed Rosellini's Other Place Restaurant, which was not able to renew their Lease, (they'd been there around 12 years or so at the time) due to the deal struck between PSB and the Building's Property Manager UNICO Properties. :-( (I had worked at the "OP" from Fall of '77 until almost Summer of '80).
The way I remember the approximate takeover timeline, is that for probably at least the last two years of my employment with the parking company, (which had their Seattle/PNW Regional Office in Puget Sound Plaza) that Branch of the Bank was where I deposited my paycheck, and I left that Company in June of '98.
(Note to self: Check on-line version of the AP Style Book, to see if building names are amongst what should be italicized, just as movie/book titles, and, (I think) business names should be. (Also check out whether it's permissible to use parentheses within already parenthetic text)).
