The Lockwood Engineering Co. of Saginaw, Michigan builds mobile grocery
stores on wheels which feature white enamel refrigerators, bread and pastry
cases and wire basket shelving.
Called Lockwood's "Store At Your Door", the C.F. Smith Pure Food Stores
of Detroit, Michigan operates a fleet of these modern conveniences. The
moving grocery store stops at the residence, the housewife steps in, selects
her purchase, pays the driver and steps out and the "grocer" moves on to the
next customer.
