A most unusual postage stamp case made from solid or sterling silver and appearing like a square version of a sovereign case with the ring and push button button to open.
Once opened the sprung holder is not circular to hold gold sovereigns but square/rectangular to hold postage stamps.
The interior retains it' original gilding and fully hallmarked for Birmingham 1891, making it a true Victorian example. The makers initials are also present W.N., I believe for William Neale.
Excellent condition, measuring 1" wide x 1 7/8" tall including ring.
