Travel Tuesday: Mysterious Stone Book in Vienna

Here's an odd little sign I spotted in Vienna last year. You'd think it would be hanging above a bookshop or library, but it isn't. Perhaps the building changed hands? Judging from the style, it looks like it was made in the first two decades of the twentieth century. Not that I'm an expert.
Austria's capital is a wonderful destination for art and culture. The museums are in old Hapsburg palaces and the cafes serve up cakes that will kill you with kindness. I got to thinking about Vienna yesterday because former Gadling colleague Pam Mandel wrote about a fun blog post about the Vienna flea market. Check it out. She's a great travel writer!
