Allegory of Flight. Scott #C1, issued on 1928. 5c stamp worth now approximately $12,5 in condition like below. There are imperforated stamps like this in pairs vertically and horizontally. And if you have such stamps then its values are starting from $225,-
This is another piece of fine stamp that fits to my collection - looks and is old, nice perforation and picture one it. Looks like Canadian stamps are one of most commonly represented in my collection. First of all there are Latvian and Lithuanian stamps. And then there are US and Canadian stamps.
