Formula One Stamps

I finally bought the set of Formula One stamps that was missing from my 2008 Singapore collection.  The face value of the stamps is $2 each.  So the total face value is actually $4 for the block of 2 stamps.  However, I had to pay a total of $6 because it was no longer available off Singpost's website.

Have provided a pic of the stamps below (not a scan )

I am not really certain that I can appreciate the design of this set of stamps.  It is a bit too modern for me and I don't understand the digital look and feel.  Would have preferred if it was real cars or something depicted on the stamps or perhaps face of some of the drivers.  But perhaps there are copyright and trademark issues.
