O-umajirushi is great for an idea of what mon were like in the Momoyama period, but what were they like before that? There are few earlier sources for mon other than depictions of battle scenes and similar. One that I have found, however, is Kenmon Shokamon (見聞諸家紋), which translates to “Various Observed Family Crests”. It’ss an excellent collection of a wide variety of earlier mon, some of which have been featured on this blog as “provincial samurai” mon. It was originally published around 1467–1470, and it features crests that were observed on the banners and camp curtains of the Ōnin War, which started the Sengoku period.(ja.wp:見聞諸家紋) It contains a variety of combinations and motifs that are rare or absent by the time of the later codifications. I recently got access to the full text of this source via Google Books and shenanigans, and it has plenty of interesting designs, featuring a wide selection of plovers and also including a phoenix, a horse, and a shrimp. It also features some unexpectedly pictorial designs that in some ways are more similar to the later Edo period designs than those in common use around the Momoyama period. Its selection of mon that combine multiple elements in different ways will be useful for those seeking to register mon in the SCA.

I haven’t had time for detailed analysis as of yet, but I present the text for your enjoyment:
