4 Little 1940s Empty Snapshots Albums

3 Little 1940s snapshot albums with thick paper covers.
And one that's lost is cover (so you could make a new one !)
The albums are empty and measures approx 4.5" by 3".
2 have space for 12 photos, 1 for 10 photos and the coverless one
and has 24 slots for photos. 
Two of them have the addresses of the chemists that processed the photos - probably given away free by them as advertising ?
