I finally took a look at an 1995-6 USPS Commemorative Album (blocks, not FDC) my mom gave me years ago and actually appreciated the panels. Broke down and bought more from eBay
at around face value.
The ones I got from my mom in original packaging, 1995-6, were 8.5x11 but all other years I got (70s-00s) and the ASPPP indicates they should be 8.5x11.25. What?
The original 3-ring binders and "photo album" pages were cheap and don't show well, so how do collectors store these pages? Thinking of getting rid of the original packaging but they don't fit in sheet protectors as they are 1/4" too tall. The cost of small mint sheet albums is overkill for such cheaply acquired material. Trimming them down is possible as I don't think there's any resale loss here :-)
