While it is still common to send postcards from one's travels, today more and more people might just opt to send images via their smartphones. But a century ago, major postcard companies produced hundreds of postcards for cities small and large. Milwaukee was no exception: years ago, visitors could send images of the Milwaukee County Zoo, the homes of Astor Street, or the 3rd Ward. This digital collection from the University of Wisconsin-Milwaukee Libraries features 755 postcards from the Thomas and Jean Ross Bliffert Postcard Collection. Thomas and Jean Ross Bliffert have collected postcards of Milwaukee since 1945, and they donated their collection to the library in 1998. This particular set of images focuses primarily on postcards produced by Milwaukee publishers like the L.L. Cook Company and the E.C. Kropp Company. There's something for everyone here, including some rare images of the long-gone rides at the Wonderland Amusement Park. Lovers of urban geography and history will be able to spend some quality time here, and it's a great slice of Wisconsin history.
