I collect Broncos Auto's have over a 10 year PC collection folder, the only knock backs have been Ben Teo & Alex Glenn on last years stuff up cards, which is totally fair call, Corey Parker has signed heaps for me over the years & remembers that I collect. Darren always politely signed for me as well, my kids are usually with me & have had plenty signed as well including their own jerseys, we always ask first,never expect & only offer up 2 or 3 cards only more if time & no others. I do not get multiples of same cards only what we need for PC, never sold any have swapped a couple. Have seen a few in public over the years but only say HI have never invaded their own time, cheers Craig
