This tiny paper envelope was made in the Victorian era to contain cough lozenges. A sweet memento of another century which makes a lovely photo prop or could be used for a craft or scrapbook project.
The envelope has not been used but as it is over 120 years old at some point it appears to have been in a damp atmosphere where the gummed flap has then sealed itself to the envelope. I've opened one to show how this is likely to tear the paper if you were wanting to make it an envelope again. Due to the age of the item it does have that old paper musty scent too.
H. J. Manfull was a chemist / druggist in Nottingham at the end of the 19th Century. The logo on the envelope has the motto of the order of the garter and The Prince of Wales feathers in the centre so I presume it was used to imply a Royal endorsement of the lozenges by Prince Albert Edward (later King Edward VII).
This envelope came together with labels from the family business which had not been used and were all remaining at the last shop to close in the 1960s.
