^^^ Yes, you're right sopas_ej,
that is the Architect's Building in 1968 & 1969 photos.
Note in the second one they're dismantling it from the top down,
it seems the top 2 or 3 floors are already gone
above: Here's another pic of the Architect's Building.
(the top seven floors were rented to prominent architect's, hence the name)
I have to thank you for posting the Bunker Hill evolution/devolution pics.
Bunker Hill is prime 'noir' territory
(featured in such films as 'Night Has a Thousand Eyes' 1948,
'Act of Violence' 1949, 'Criss Cross' 1949, 'Kiss Me Deadly' 1955 among others )
And yet it's still a mystery to me.
They leveled and destroyed it so well that it's hard for me to place it now.
(where it was exactly, or which way it ran, how large an area, etc.)
Anyway, the pics you posted helped clarify it a bit for me.
But it's still somewhat of a mystery to me, and maybe it's better that way.
