Here's a lesson in how NOT to soak off stamps.
Put these two Venezuelan stamps into soak the other night. One is damaged already, but I was interested in the stamp with the overprint.
Got preoccupied with something else (SCF I think!), turned off the computer and went to bed. Totally forgot about my little charges.
When I retrieved them in the morning, this is what I found.
See how the cancels have run?
Let that be a lesson to you children. Keep your eyes on the prize!
