G-Valley Industrial Museum's 'Mr. Guk-in's Growth Album' is a family class for children in grades 4–6 and their guardians. The service period is listed as 5 September–19 December 2026, with 90-minute sessions on specified Saturdays, 10:00–11:30. The notice excludes 26 September, 3 October, 14 and 28 November, and 26 December; check the calendar for available dates. Families solve industrial-history puzzles in the gallery and decorate a card wallet. The activities use the third-floor exhibition hall and ninth-floor classroom. Each free session takes eight first-come teams of two or three people including guardians. Staff confirm ages and numbers by phone after application. The session may be cancelled if fewer than three teams have enrolled as of 17:00 the day before. Arrive at the third-floor information desk at least ten minutes early. Register through Seoul Public Service Reservation. The reservation platform's summary indicates cancellation is unavailable, while the detailed notice says that cancellation by phone is possible up to two days before the class. Confirm the exact cut-off with the museum on 02-6734-6910 or 6909. No-shows or same-day cancellations may restrict future museum education participation for one year. The address is 38 Digital-ro 26-gil, Guro-gu, Seoul. Registered participants are offered 90 minutes of free parking through the information desk.
Museum staff may take photographs or videos for institutional records during the session. The official notice warns that families who do not consent may be unable to participate; check these consent and image-use conditions before booking. For a party of four or more, separate booking accounts are required because one account can register at most three participants.
