Back in July, I took a look at the florist & monument businesses clustered around Greenwood Cemetery a century ago. 734-6 Fifth were once part of the J. Condon florist business, there from at least as early as 1903 (probably earlier) & still on the avenue in 1941. The Condon greenhouses are long gone, but the building at the corner still stands on Fifth. It looks like the auto repair shop lot at 732 Fifth was once part of Condon's (half a greenhouse?), and it too was recently sold. No change in usage indicated there as yet..
P.L. Sperr, & er, Google
