richad nickel images of frank lloyd wright's a.d. german warehouse

i've spent months looking for richard nickel images of frank lloyd wright's a.d. german warehouse (1921) located in the architect's hometown richland center, wisc.

i found a contact sheet and digitized the images posted here. i cannot recall the date offhand, but must be 1950's. 
the individual standing in front of the ornamented concrete frieze is the building owner. i will have to revisit nickel's notes on this visit.
