The A-Board Influx

On my way back to Preston Train Station I was confronted with A-Board clusters at particular pavement corners. Charles had pointed out the Preston City Centre A-Board influx, when I had my initial tour of Preston. Most of these A-boards are A2 in size, apart from the larger chalkboard in the photo below, peaking above. I wondered if anyone might purchase the available XL A-Board (H:152.4cm x W:91.44cm) in the future, then I wondered if I might make the XL A-Board in the near future?
