"Help"ing Hands

Here is a photo of John signing a Help album at the 1975 Helping Hands marathon.  I think he is wearing this denim hat which he later signed and auctioned off for the charity that day.   The hat was later auctioned off at a big-named auction house (and most likely made much more for the seller than it originally did for the charity) and I thought it was a unique item, so I saved the photo of it in  my files.   When I spotted this John photo I recognized that hat although it is difficult in that old black and white photo to tell 100% if it is the same.
