Department of There's an Internet Business for Everything: Yellow Images sells blank products ready for you to superimpose your own brand/product. There's something so soothing about a plain object not covered in all of the cruft designers are paid to create.
The Henry Parkes Centre is located in Parkes, NSW. WorkingType Design worked on the exterior and interior signage units — the emphasis being on colour, boldness and scale. The Centre houses a rather diverse group of exhibits: The King's Castle Elvis Exhibit, Parkes Motor Museum, Parkes Museum and Antique Machinery collection.
If you are planning to sell your book at places other than bookstores, you might want to consider a portable display banner to attract attention. Lightweight, retractable banners are widely available and with designs printed in full colour at high resolution, they can be quite striking. Prices are low and preparation of artwork (a service offered by WorkingType) is usually similarly inexpensive. The banner shown below this post features "The Sunny Side of the Street" by Maria Stefanidis.
