Whenever possible I try to find these crebs with a little extra. Just picked up the insulator with a nice bubble in front skirt area. Would have prefered it was on the #20 rear side so I could view bubble and number at the same time but I guess one can't always have everything. At least I didn't have to pay out the nose through Egay to be the new owner of this gem. That is most likely because the seller didn't high light the fact the bubble was there in main cover pic. I spotted when viewing his other pics. As for color I am pleased that it is different then the two other #20 crowns I already had. It also has an above average amount of dome glass then the greater majoriity of the beehive crebs have. Must say I am ery pleased with my latest find. Hope you all enjoy and appreciate as much as I do, Thanks for looking. If anyone has a reasonable #22 without ER on the front skirt let me know. Maybe we can make a deal through buyng or trading.
