Everyone loves this one - a jumbo fine-art cotton rag version sold at The Western Way, but this one's a smaller, budget-friendly ready-to-hang version! There's also an A3 available.  
 
This artwork is designed to be affordable, it's printed & mounted, ready for an A4 size frame - print is 15.5 x 24, mount A4. I recommend Home Depot from Spotlight as they're deep and have the spring clips to accommodate the print & board - measures approx. 6mm.
