There were lots of liquids in bottles of all shapes and sizes. They tried hard to sell me some of the dark liquid in a Rum bottle. I was told that I could rub it on my skin or drink it. I was assured that it would cure everything. I declined.
Then they wanted to sell me some cigars.
I felt badly because they were very friendly and obviously could use the money. I spied the collection of old books for sale for one CUC each (about one dollar) and picked out a couple to buy.
One was a History of the USSR, written in Spanish, and published in Moscow.
The other was a history of the Trujillo conspiracy, one of the first CIA backed attempts at overthrowing the new Castro government. The book had some interesting photos.
I ended up giving them each another CUC for their time and photos.
