Fully-embroidered. Decent detail for a 3" patch.
A second variation has been identified here without a blue border on the yellow delta and lacking a red border on the shield. Ever so slightly oblong vertically. I was not sure if this was intentional, but a second copy was also oblong.
This patch was collected in a set of other 3" patches, also dissimilar from "original" A-B Emblem issues.
I am going to tag this collection with the "apollounk2" tag. Leading candidate is Cape Kennedy Medals based on the Apollo 17 patch in this set being a CKM patch.
