I routinely dump interesting postcard images into a folder until I gather enough from one company to become interested. When I saw I had 3 from the Iowa Seed Company, I took a look for catalogs in the Biodiversity Heritage Library with fair success! Later I'll post some of their most interesting advertising art from the catalogs...but today here are the postcards and a few snippets about the company.
"8,600 acres in seed growing"
While I'm not sure, I believe this "we pay the postage" engraving was used by printers around this time for many companies...it isn't unique to this catalog. Sure is wonderful though!!!

This is the address on the postcards.
