Great job Butch and Lurch
True. This image has faded unevenly so there is no ‘quick fix’
Add a levels adjustment and use these numbers
Red 149 0.82 238
Green 30 0.93 224
Blue 36 1.31 187
That gets the image close but still needs some ‘fiddling’
There are signs that the background was blue so I added a layer set to colour and painted the background blue
A little more paint on the faces
Added another levels adjustment to lighten the edges
And a bit more ‘fiddling’
There is more that could be done but its getting there.
