Flag Stamps

as I've already mentioned I have a small and growing collection of US Flag Stamps. Last week I purchased a set of 11 plate blocks representing the first 11 (I believe) stamps that portray the US Flag. My intent is to place these in an album alongside a single stamp and maybe a cover with that stamp. Anyway here are the first four ...

1) 1945; Scott #938; commemorating Texas Statehood, US Flag over the Texas state flag ...

2) 1952; Scott #1010; commemorating the arrival of the Marquis de Lafayette in America, US & French flags flank portrait of Lafayette

3) 1957; Scott #1094; "Old Glory", commemorates the adoption of the 48-star flag

4) 1959; Scott #1132; commemorates the adoption of the 49-star flag
