Dear Imran,

Thanks for your request. This is a painting made in acrylic paint on cardboard with the measurements 56,6 x 39,5 cm. It depicts a warrior from the famous computer game Halo. It is signed in the right corner with A. Guard and dated with "2010". Sadly there is no artist with such a name mentioned in auction record lists or similar databases.
An estimation would be from 50 to 100 GBP.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
