Toronto. George Dunbar sent me an email yesterday with a link to liveleak,com. The link takes you to a 9 minute video (with music) showing a number of photographs spanning the mid 1800s to mid 1900s.
According to the site, all have been colourized although colour film was available through the 1900s. Colour film was rare during the first half of the 20th century making coluorization of black and white images most likely.
