<p>Hello!<br> I purchased some negatives which were billed as original vintage 1950s B&W - however, I noticed one of them has no frame numbers or information in the rebate area. It is exactly 2-1/4" so I don't think it's a copy neg.</p> <p>Could this be a frame at the very end of or beginning of the roll of film where there would be no rebate markings?<br> Thank you so much.</p>
