How about a picture of his head and forearm cut open, with the phrase ‘Mark Robins, oozing sky blue blood’?.
On a serious note, I think it’s a great idea and a deserved gesture. Personally would go for a Sky blue background and black and white portrait of MR. Difficult to pinpoint correct phrase or wording. Simplicity might do it ‘Mark Robins’ Sky Blue Army’? It’s the one we sing the most, won’t ever go out of date and can be sung as it’s hoisted across the main stand of the packed out Ricoh at 3pm on a Saturday. May not work if we are still at St. Andrews, socially distant in the stands with 3,000 people in there.
Happy to throw £20 in once design finalized nevertheless. Great idea.
