I believe those markings are a part of the woods matched slices. The back slices on the guitar appear to be from the same wood source. The 14,950.00 price was AUD (stated in the footer) and when I reloaded I got the 10,327.46 and the footer changed to USD. The pricing is driven by a cookie stored on the local machine. I deleted the petesrareguitars.com cookie and it reverts back to the AUD amount and footer. It then sets the cookie again for USD (this is based off your IP address location).
