A stamp collector decides to put all his stamps in a new album. If he puts 20 stamps on one sheet, there will be some left over; if he puts 23 stamps on a sheet, there will be at least one empty sheet left in the album. If the stamp collector is presented with an additional new album of the same kind, each sheet holding 21 stamps, he will be left with a total of 500 stamps. How many sheets are there in the first album?
