Feel free to use our logo to publicise the WaLSA-related activities. The following file formats are provided for various purposes. EPS and PDF files are vector images designed for use at any size (the preferred formats). PNG files are smaller in size and are good options for digital use (e.g., presentations or web). All files have transparent background, thus, depending on dark or light backgrounds in your work, either white or black versions of the logo, offered below, may be used.
