small yellow 'pressed glass' (?) border/corner piece from an old front door

I've had this little piece of old glass for probably 20yrs or so, having "recovered" it from the rotted remains of the wooden frame of a Craftsman styled (I think, maybe Victorian?) window/door of unknown actual age or provenance, which at the time had been stowed (badly) in a dirt-floored garage owned by my then landlord.

[what was I thinking...why didn't I manage to swipe the whole thing, or at least all the glass?? there must have been some reason I've forgotten about... <sigh>]

If I do remember correctly, this was a corner pane in a border made of similarly sized but variously colored flat panes of stained glass ("art glass"?) which surrounded a square (rectangular?) block of clear glass panes, in all forming the window panel of an entry door. (outside chance it might have been an actual decorative window panel instead, but I think it was a door?)

It is 4" square, the pattern is raised on one surface while the other is flat. It is likely that the 'edge chips' have always been there, since its actual edges were always unseen behind glazing/woodwork before. I have to think it is late 1800's/early 1900's.

I'd love to learn more about it if anybody has any further clues to share?! Meanwhiles, it's still a nice suncatcher... ;-) :-)
