There are many tall, slim stamps from many countries. What I do, using your example is use a 20mm mount vertically, with the left side secure to the album page. Sometimes I'll secure both sides (Do not apply moisture across the back of the mount. Apply it to each side, keeping away from the center seam.) The top and bottom are open, but the sides are secure. I find that the stamps are much less prone to slip downward than they are to slip side to side.
I am busy compiling an Israel album, but the one thing I have not yet resolved is the best method of mounting the stamps.
For most of my albums,the standard top loading mounts have served me well. However Israeli stamps are collected with "full" tabs, this consists of an informational tab and in many cases an additional strip of selvedge resulting in some very tall stamps in relation to their width e.g 20mm wide X 65mm high. It seems then, that it is likely that the stamps will tend to swivel out of tall narrow top loaded mounts. So I was wondering what others do.
A friend suggested using split mounts turned vertically, which could be a workable solution but I will need some method of sealing the open side - now the bottom. I have also heard complaints of stamps being damaged while being inserted or removed from split mounts.
Thanks,
Clive
