Saw some attributed to (or guessed as) Alley, which reminded me that wasn't the first time I saw them attributed to Alley, and I don't know enough about any of them.
And in another conversation, about Akro Imperials being thought to be silver oxbloods, I did think of your Hy-Grade bag with the milky ones, and Hy-Grade bags in general, containing swirls ... and I wondered ... were all those swirls Akro .... or did Akro maybe buy some from Alley after all.
Do you see differences between the ones you think of as Akro and the ones you think of as Alley?
