The star of the lot was the one at the middle right. These intricate cards are hard to locate in any condition. I gave given them an attribution of "probably Whitney" in the 3rd edition. (Two are shown on page 277.) No data has surfaced that prompts a change to that attribution, but I am remain optimistic that some marked box will surface one day.
This is a really great box. I've not seen it before. The JOLs along the edges and the use of the fat font are reminiscent of Dennison. However, Dennison was disciplined about marking their goods, so I tend to think it wasn't produced by them. (By the way, Dennison wasn't perfect about marking their items. A few, like the "Whoopee" diecut on page 144, escaped the factory unmarked.) This box has super graphics and would have made a splendid addition to my collection. I wish I had seen it in time!
The seller left considerable money on the table listing this with a BIN of $150. This is perhaps the earliest Beistle packaging I've seen and probably dates to 1918. (Beistle didn't even have their name on the envelope, or a stock number or even a witty description of the contents.) If I had seen this I would have excitedly added this to the collection. I would think that owlcreek15 could have gotten at least double, and perhaps more, than the $150 BIN price assigned!
These cards, marked made in Saxony, were manufactured sometime right before 1920. Although two designs are being offered, a complete set is comprised of four designs, all shown on page 286. The other two designs show a perched owl and a snarling black cat face.
These great invitations were actually made by Whitney. This firm, out of business by 1943, rarely marked any of their Halloween goods except for postcards. I doubt the envelopes are original to the invitations since the fit usually isn't as snug as the seller's description indicates.
