It's possible, it's just that most of the stuff tended to get added in chunks as the issues were, presumably, being written, and Kibblesmith was makking pins so he could show the artists/editors what he was talking about in the script. so all the chess stuff was one batch, along with the shot of the library, all the cowboy/cards stuff was in another block, etc. but some other things have never shown up, like the monkeys, or the matchbook, or the girl box (that's actually what it's called. it's from a hotel in Los Angeles) so... they may have been pinned early as he got an idea, but they may have also just fallen by the wayside, because creative ideas are always shifting until they are put to page. But in hindsight, with the addition of the 1920s/30s style penny, that might fit with the match book, which has been chilling in there since forever, they are both from roughly the same era, of late 20s/early 30s, so... (i still want to see Loki in a speakeasy SO BAD... but Canada never did prohibition, at least not on as large a scale as in the US) I dunno, keep an eye out for some of these to make an appearance i guess, for more Loki dressup fun.

If we continue to see flashbacks where they add to Loki's past, the context I would like to see Lady Loki in is waaaaaaaay back, in viking times. I just kinda want that bit of the myths where Loki took the form of a woman and married a mortal dude to be added back into Loki's history.
