Seeking Flag Over Porch PNC Material For Exhibiting

One of the goals I've set for myself is to exhibit Flag Over Porch plate number coils in 2024. I've spent many years acquiring material for the purpose of showing it at a stamp show, but I'm seeking more diverse material. Anything from design materials, stamp announcements or literature, printing/perf or die cut errors, postally used covers, ephemera, etc. would be great! If anybody has unique (or not so unique) items that they're willing to part with, please post here or message me. Thanks in advance!

Join the party. I am also looking for unusual FoP material.

Here is a 2913 #44444 on top I just picked up.



Full #s on top are quite uncommon after the Transportation coils.

Eyeonwall, that's a great strip I've never seen before! Glad you were able to add it to your collection. Hope to find something like that for my collection/exhibit some day.
