19th century Magic lantern glass photo slide , This was identified in my collection as Thames number 12 but the description is not labelled on the slide. The slide does have full frames still intact, shows building and Derrick? The photo slide does have age and I suspect would show fade in a photo print. Note I send my glass slides only by overnight courier north island and two day courier to the south. A signature is required by the courier and not a post box address.
