The vend-a-goat is a real advertisement, self-promotion postcard for Dublin Photography. Some one cropped off the caption which says,
"We've all been there - you put your money in the machine and your goat gets stuck. This slice-of-life photo by Joe Lampi recreates this everyday mishap so faithfully that it leaves people nodding their heads and saying, 'I know that feeling.' Ironically during the shoot Joe lost fifty cents to a Vend-a-Tuba."
