Pictorial Guide Issued by CBP or USCIS showing all forms of Acceptable Evidence of LPR?

[Indomex 10]

I am trying to find a document issued by any DHS or other US Govt agency that pictorially shows all the different documents that establish proof of LPR. Specifically, I have an I-751 pending and have an I-551 stamp in my passport and will be traveling soon (I don't have expired GC and notice of extension). I would like to carry a printout of such a document so the airlines and other authorities don't give me a hard time when I try to board a flight to the US. I did several valiant google searches and found nothing.

Has anyone ever found a doc like this?

thanks in advance

I'm not sure what you mean by "proof of LPR". The only thing you need to prove that you are a permanent resident is a valid greencard - there really are no other documents you need, or that you can show, as proof of that. You say you have ROC pending - didn't they send you the extension letter? You can always print out the relevant pages/instructions from USCIS website that explain the situation of pending ROC and extension of the previous conditional GC, but obviously those are not formal documents, merely printouts. I highly doubt there's any sort of illustrated guide for these situations..
