Union Label

Of interest to you label experts. Here's a cover I purchased at auction last night at the stamp club, with a 1948 National Union Label Week sticker. It's hard to see from the scan, but the envelope is also embossed under the label
??EGOR UNION 'S' BOND
INTERNATIONAL BROTHERHOOD OF PAPERMAKERS REG-390
UNION MADE

Can't quite make out the prestamp on the envelope. ?OGIE? Ill.

Lots of fun for a couple of bucks!

Hey, is that the INION LABEL that the jingle sang about?? I always wondered...

Gonna need a closer closeup for these old, tired eyese of mine.

that better?
