In the 1930s, my grandfather, Israel SIGAL, had a small textile shop with his name on the front, at Weyprechtgasse 3 in the 16th District / Ottakring.  The landlord was named Kretschmer.  Although the shop was vandalized and looted, the building survived the wartime bombing and presently holds a physician's office.  Would photos exist of the 1930s storefront before the atrocities began, in city archives or elsewhere?  Any positive suggestions would be much appreciated.  Many thanks!
