1978 (06) Coronation - Philart - Windsor Castle CDS (Coronation Day)

Unusual Philart cover......

Windsor Castle CDS (Coronation Day)....

I've seen this CDS Date on a Post Office cover, so it seems that possibly a few were serviced, but still highly relevant to the issue.....

Cover has residue top left area- might have been another label of some sort, but mentioned for accuracy...

Code: 67005
